[LTUDSM]

need help from you guys,thanks alot

sounds like a vac leak, check your vac lines and ic pipes.

 

[LTUDSM]

when the car is idling my vac jumping between 15-20 is it normal??
i don't think there is the vacuum leak,because if i got the vac leak the car would not loose the power (will boost)
My IC pipes are really tight,cause i just got cleaned up my IC so when i put everything back i tight the Pipes as much as i can

What was the a/f reading from the wide band? Not trying to be a dick but if you can take a couple of #'s from a display and know you are lean, you should have enough knowledge to troubleshoot your problems before giving all of us a vague descrition and asking us to solve it for you.

 

[LTUDSM]

i got my Air/Fuel ratio gauge and it showed me that I'm going really lean,so i went to the ExtremePsi store and ask the guys to hook up the WB O2 sensor,and they told me the same thing that my Air/fuel ratio showed me (Running really lean)and they didn't gave me any numbers,so i don't know what to do,thats why I'm asking you guys to help to solve my problem
yes,i did the boost leak test,and i got leaks on 27 PSI from my Bov

if your timing jumped then your valves arent opening at the right time and that would cause the vac to jump around.

 

[LTUDSM]

and when I'm driving my car it's sneezing and sometimes it shoots black smoke (when I'm at WOT)
is that for a pulled timing??

 

[DSMstatus]

if i were you i would pull the timing cover and check the marks. and when the cam marks are lined up there should be 15 teeth on the belt between the 2 cam sprockets, make sure you all lined up in there. sounds to me like your valves arent opening at the right times.

 

[LTUDSM]

Can you get me the picture of the Cams please,i want to take a look and compare with mines,i never did anything with the timing or camgears

 

[DSMstatus]

this is the best i got.

 

[LTUDSM]

and where is the marks?
and how they suposted to be??

[LTUDSM]

Thanks alot DSMstatus
tomorrow im going to work on it ill post my timing picture tomorrow
Thanks again

 

[DSMstatus]

no problem, just be carefull with it, also explore vfaq.com, it will become your best friend.

 

[LTUDSM]

i checked the timing today and it was good,the marks are in the same place where they should be
what else could be

 

[DSMstatus]

next do a dry and then a wet compression test to check rings ang valves and head gasket, you can find instructions on the vfaq site.

 

[LTUDSM]

I got my engine rebuilt a half year ago cause my timing belt was fu*ked up,thats why i got rebuild it,I got the metal head gasket
i don't think that my Head gasket is blow i did a leak down test and the compression test ,i got 154 for all cylinders

 

[DSMstatus]

hum, well i cant think of anything else, try asking the wisemen, they know a lot more than me thats for sure.

I see no wideband listed in your vehicle profile, nor do I see a way of altering fuel delivery. Update your profile with every mod on the car so we can better help you, at this point I'm ready to tell you that the blinky light AF meter doesn't mean a damn thing since that it all you have listed as having.

 

[sherms_gsx_tank]

when you rebuilt your engine im going to assume that you took the intake manifold off and when you put it back on did you do a base idol procedure cause you need to do that. it sounds to me like your manifold is rocked all the way up and thats why your running lean. im all the way down (which i need to do it to) and im running REALLY rich so try that out

 

[LTUDSM]

the guys from TurboTrix did the engine job,and they did a high quality job,i paid them 2300 to rebuilt the engine,so now I'm trying to do the best what i can do by myself,I'm tired to give the money to the mechanics

 

[sherms_gsx_tank]

yeah i hear you but if you take a good pic of your manifold i could probably tell you if you need to do the base idol procedure. cause to me thats all that seems to be the problem. it might just be you need to re adjust your bov too if you have an after market. sometimes there simple problems so look at those if you havent already.

He said he went to ExtremePsi and used their wideband. Ok now back on topic question did your CEL come on, you didnt say anything about it but i figured I would ask anyway.

 

[LTUDSM]

No, the cel is not coming

and my idle is very very bad,sometimes my car just stall at the light or at the stop,and I'm tried to get pooled by any civics and s*it like that,please help me guys, what is i post my timing pic,if it's gonna be easier for you guys?

 

[95-talontsi]
