can we please get rid off this myth that back pressure is a good thing , it is 100% false . espicialy on turbo cars . The best exhaust is no exhaust . you want velocity or the exhaust gasses to exit the car as fast as possible so it can take in more air and make more power.
Are mafs are a different design then most mafs , most have the hot wire kind , we have the vortex something any ways u cant clean it with maft cleaner , you will just ruin it . I thought the same thing when i first my 90 laser , so i went to autozone and bought some maft cleaner and was reading...
E bay is OK for intercoolers and piping but fitment is usually an issue , depends what maf you have or if you even have a maf or if you have relocated your coolant box.
I think E85 or corn juice just has a really high octane rating which is good for turbocharged cars .The higher the octane rating the higher the the temps can be in the combustion chamber , so more boost ,. See if it gets to hot then you get knock or pre ignition before , when the plug fires...
Dont know if this helps you at all but what i did was run a wire from the fuse box to my console and put in a switch and ran the wire to my fans , so if i want them to come on i just flip a switch. Just dont forget to turn them on .
Had the same problem, I just adjusted the nut under the console and it was fine . How many clicks does the your e-brake make when you pull it up all the way?
I have always been told that if you line up the piston rings gaps that you will have to much blow by and not enough compression and i always just went with it , but now i have this friend who tells me differently . All he does all day is build high performance chevy 350 motors and he told me...
Ok have some questions that have been in the back of my head since i was getting into cars , warning you they might sound stupid.LOLWhy is back pressure good for N/A cars?Could you make a adjustable wastegate , where could just flapper open when you wanted from inside the car?When you...
Yeah then I would look into your TPS or ISCCorrect me if Im wrong but i think if the TPS was telling the computer false reading about where the throttle was , it would purge the injectors making your idle surge.
well would a bad cts or 02 sensor do this . It also has a really unresponsive throttle response i mean when its bouncing back and forth between 2000 and 2300 i give it gas and it stays at the same rpms and then if i floor it , it will go up in rpms but after a couple of seconds. Sounds like TPS...
yeah i sent them an email just wondering if there is anybody else that will do it. Also does anybody know what ecm charges for a rebuild and can you tell them what you want rebuilt or do they just replace everything?
I know that you have to do stuff to get a 91 ecu to work in a 90 car but is what is happening to me , would that happen from putting the 91 ecu in . Because then ill just go find a 90 ecu.
I bought the ss braided lines from bonehead performance for my oil and i love it , you can have work on so many other turbos .And you dont have line everything up for the banjo bolts , so much easier.
just remember liquids dont compress and there is a chance of hydro locking your motor even though my friend took a hose and put it in his intake of his ranger and it still didn't lock up for a while.I put mine in the vac line off the brake booster and put the rest in my gas. But mine didn't...
Ok guys now i have a new problem , when i start my car it idles a 3000 grand staying still then as soon as i let off the clutch the car idle jumps from 2000 to 2300
back and forth and back and forth . Does this sound like boost leak problem or do i need to adjust the TPS and ISC also i have put...
Ok guys i figured it out , today i was planing taking of everything i had put on the car but before i checked batt voltage again and i was just putting in odd places on the pos cable and you know that metal plate that attaches those fuses to the batt it was only showing 10 volts so i tightened...
Oh i didnt know that, but would that cause the car not start and turn of all the lights and radio . And also the car started before with the new ecu but only a couple times. Let me call the guy and ask what year of dsm he pulled from.
i have put in new ecu would that cause these problemsi have checked the connections . How many grounds are on the car and how many would have to be undone to cause this problem?steve ?
ok checked the posts and terminals there fine. Is it possable one of the wires is grounding the power somwhere but if it is how are the lights even on?
I'm very working good working on my car if there mechanical problems i just hate electricity . Does any body else have any ideas why the car is not cranking.
Ok i put my battery in my moms car and it worked fine . also while doing that i had some sparks flying in my moms car when disconnecting the batt it melted a huge mark in to one of my half inch wrenches lol. but anyway has anybody had this problem ? the car has its lights on and has perfect...
I checked the battery voltage before i turn the key to the on position then i check after and it is zero but i will 1 minute or so and check voltage and the batt is back to 12 volts so confused is it possible that the power is jumping somewhere and not going to the ignition .Does the ecu...
well now the car wont even turn over i have no power but i have 14 volts at the batt so confused .I tried jumping the car and nothing then let it sit for 10 minutes came out and the car lights where working but as soon as i cranked it would die it wouldn't even turn over i know its something...
Ok today i picked up an eprom ecu and MFI relay and injector tranzistor for 150 bucks and put on my car and it started and stayed running but only if i would give it gas and it would jump around like crazy with rpms , like i was giving a steady amount of gas trying to hold it aroung 2000 rpms...
I just dont get how my MPI could be bad if the car starts and then dies , also since i put my mfi relay back in , it has started making this clicking noise. Once when i crank and once when i stop cranking any ideas?Also someone told me to check the fuel filter but how could it be clogged if...
