where can i get a new BISS screw, part # would prob help i would rather go to auto zone but if i have to get it from a dealer then tell me

after installing an adjustable fuel pressure regulator i got some issues. it was a cheap unit and i cant adjust pressure below 65 or so. If i take off the vacuum it doesnt change the reading. i have a lot of speculation on whether it works because it seemed used when i got it. Is there anything...

I got a mix of parts and dont remember what my tps/throttle body is. What is the difference between 1g and 2g tps sensors. I wanna get a used tps but dont know which i got. Im pretty sure its a four prong so is that all i need to know cause a guy on ebay has 1g 3-4 prong tps's?

My fuel pressure gauge reads weird. I cant get it to adjust to 43 it goes to about 30 then if i tighten down the screw it goes to 0 and i can feel it surge with the engine idle. The pressure regulator will jerk with the surging pressure. Any ideas? is this cheap fpr just broke or what.?

Bought a cheap fpr and the adapter to the fuela rail is leaking out the fitting. I need to find an adapter to fit to our fuel rails (2g gsx) that just has a metal fitting piece to conect to the hose going to my fpr. Any ideas.? I might try some jb weld on the piece but it didnt fit well either...

i need a new ecu. i have a 95 gsx 5sp. Does the ecu have to be from an awd car. I would think it did but im having trouble findin one and hope a gst ecu will work.

been running rich forever, becuase of the fuel pump and many mods., like 1g head and other stuff. should i get an afpr to address the fuel problem or get an safc. if i get an safc it would be non digital and very limited, or this afpr...

can bad compression cause idle surge? thats it.

where can i get some cheap new coils???

95 gsx, changed plugs wires and checked power transistor. Ive also checked the secondary resistance of the coils but i can figure out the primary part of the coil check. The car has weak firing. It is not worse under boost or i would automatically think coils. It just seems weak in general...

Was wondering if anybody was using the original apexi safc, there cheap and i just want to get my o2 voltage down a bit not fine tune.

i have a 1 gen intake and head, i cant remember if my throttle body is 1 gen cause i bought it like this but i think its likely that if the 1 gen flows better that i have that one. I am lookin to get a new isc and i dont know which one, whats the difference?

what i said, basically it misfires across the band. It is not boost or rpm dependant it will misfire at anytime. If i reset the ecu, unplug the battery, it will go away for about 30 hw miles then it hits again. If i reset it after every use it wont happen but i imagine there is still something...

bought my 2g with a 1g head swap. im not sure and was wondering which CAS sensor do i get cause i think mine is bad. I dont know if the 1995 gsx sensor is different from the 1g sensor or if it fits on a 1g head. I was just wanting some help on which year to order a sensor from. Any info on...

i posted about car stranded and fp dead but its not. so i guess its ignition, i put a volt meter on the plug wire aand grounded it to the car and it didnt read any real voltage. how can i test the ignition system? i was getting rich/lean reading before this happenedand the car was running weird...

2g awd. i wanna do the fp myself. i have a haynes book but if anybody has any pointers. Is it very difficult, it doesnt seems so but that always causes trouble. i know i need a new seal but other than that?

car died when driving, i was gettting low readings on my voltmeter connected to the o2 sensor and car died. it turns over but wont start and it doesnt smell like its flooding itself so i dont think its getting fuel. I have a 255 fp and i believe i used to be able to hear it with the ignition on...

aside from my throttle bouncing up and down can a tps cause the car to run bad because i am loosing power after 7 psi

2g i believe i the tps is located on the front of the throttle body next to the fuel rail? but to adjust i thought there was a screw but it looks like its more like the cas sensor in that u have to loosen both screws then turn the whole unit.? so this is correct sensor and you have to rotate...

i run lean about 7-8 psi, car starts to jerk a little and loose power. i get low messed up reading on my voltmeter from the o2 at this time. i just swapped the injectors and the fuel pump is a huge 255 and i can hear the loud ass thing runnin and it isnt suppose to be old so i was wanting some...

seems like i got a boost leak but ive checked it all. my voltmeter on the o2 sensor reads lean right when the studdering occurs and i can boost more than 10 psi but i just got it set at stock cause the bogging down at 8 psi. its only boost related so its not ignition but may be related to fuel...

i get what i think is a boost leak right at 9-10psi and i only get 15 vac instead of 19-20, so im pretty sure its a leak but i cant find it any help?

first it was supposed to have 550's but unless there augmented they say 450's on the side, then it had a blown head gsket but i replaced it. it still runs rich, as high as 1.05 on the voltmenter. it has a 1st gen head could that have anything to do with it? i am really starting to hate dsm's

my car was rebuilt before got it but so for it didnt have the injectors from the receipt it said it did and the head wasnt brand new, it was also poorly put together so im doubting if the head is 1g but is there anyway to tell its also suppose to have a 1g intake mani

i think there stock but my injectors say MDL 450 on one side and 95H IND-018 on the other. My pistons say 63DT FI 0.50, i believe there stock but i was told that i had 550's and ross pistons!

how much boost can i run on stock 2g inj with no s-afc, ill richen up a lil with the maf screw but thats all to tune with. im sayin 18 psi?

i ordered parts from dsm parts and i was wanderin how long it takes, it didnt give any shipping options or let me track it

i have a 95 gsx with a rebuilt bottom end and a 1g head will the normal 2g headgaskets and bolts work to replace mine. which ones should i get i want to get some decent stuff prob arp studs but need to know if they fit and what kinda gasket what price should i pay

given that i have a 2g and cant use the awsome knock sensor waring built in to the new S-AFC II, should i get the I instead cause it is quite a bit cheaper. Has anyone ever had problems with a S-AFC breaking cause i was initially set on a warranty but i might get one without if they dont seem to...

balance shaft broke and found it in my cam gears, what happens if i leave the belt off and drive it cause i didnt know it broke for prob a day or two and nothing seemed to happen??what happens long term of no belt??

1995 gsx while doing my water pump i think my timing belt sliped when i loosened the tensioner. it wasnt in time where the marks lined up cause i was just going to mark it myself but i waited untill after i loosened the tensioner. now when i hand crank over the engine it stops like a valve is...

cant get the crank pully center bolt loose, a few tips would help

do i need to remove the timing belt pulley, it looks like the right side water pump bolt is directly under it. if i remove the pulley is the automatic tensioner thing connected to it? and do i have to remove that. i cant barely see anything to do the install i have the mount pulled and the...

:dsm: school sucks and i lost my grants. i got a loan and i want to sell my gsx. car has 120k on body with rebuilt engine and new parts engine work done 10k ago with receipt: ross 9:1 in the fully rebuilt bottom end off 99 gsx entire brand new 1g head used 1g intake and blow off new...

2g gsx, i am in the middle of doing my water pump. i can only work on it on the weekends but i want to do it without removing the timing belt. i think that the timing belt tensionere might be in the way but at this point i cant see it. i have the top two bolts out of the water pump and for the...

i know this is a very bad idea but i figure i should atleast post what happens. im runnin at an o2 voltage of 1.08, ive hacked the maf to get that voltage that lean. so it mmust have been like 1.10, its going to be a long time before i get an safc and i dont want to burn up my new o2 sensor so i...

ive got a 255 fp and need both an safc and afpr but which should i buy first to help with my rich condition (550 injectors) ??

i have unplugged my o2 sensor to see what happens..the car runs rich.. and it still runs the same with it unplugged and i still dont get a cel, with it running the same unplugged is it safe to say its no good or what, im running rich anyway i think cause i dont have an safc so could you tell the...

if you are getting 18-20 VAC on the boost gage at idle, is it still possible to have a boost leak at higher rpms or would it show up at idle too

ive posted before about getting bad gas and no power, i was told by the shop who built it that with running 550's and a 255 fp that it would run good without an s-afc but a little rich not too bad. i bought it like that and it was still on break in miles from a new engine rebuild. I posted about...

i have a 1g head and intake but do i necessarily have a 1g fuel rail or could i have either, are they even different??

i am gettin accesive vibration when going into higher rpms and i think my motor mounts might be little worn. the vibration doesnt bother me actually kinda makes it feel more mean, but what kinda wear on other parts could i see from not getting new mounts for a while (assuming there worn)

i was readin a thread and someone wrote that if your vac reading at warm idle is between 17-20 you dont have a boost leak, this seems way to general to me but i was just wantin some feedback

where can i get a new BISS screw, part # would prob help i would rather go to auto zone but if i have to get it from a dealer then tell me

definently a newb question but when i remove the cat do i get an engine light, if so wouldnt it send it into closed loop and not use the o2 sensors, if so then does a s-afc still control the rich/lean?? that was about three different questions thanks for any help

i bought a 95 gsx with a rebuilt engine still on break in miles. After the easy miles were gone i started noticing that i was gettin 10-15 miles to the gal. I have 550's and a 255fp with no s-afc so i know i am running rich and i get a lot of black smoke. i tried reading the o2 voltage but it...
