HESITATION Or !!???? PLZ HELP

[racer]

Ok for example: I start the car,shift to first,unclutch and when hit the gas pedal,it goes down but the car wont begin acseleratting in this very moment.It'll have like a 1-1.5 sec lag and then will kick.That sucks cuz I cant launch good like that.It doesnt do it all the time.What could that be??!!!

maybe your motor mounts are broken, my car did something like that before i replaced them

You need a datalogger. It could be a few things. Maybe your timing is being retarded, or it's something simple like a vaccuum leak (exhaust or somewhere else). It's probably the latter. I had a problem with my "slip" flange on my catback exhaust not mounting properly, and the shit would just come lose (happened after the turbo upgrade, probably couldn't take the added pressure) right at the cat. It caused the same 1-2 second hesitation you describe.

well Im N/A and My ehaust is new with test pipe and has no leaks,no vacume leaks too.I do not know how to work with datalogger and I dont have one either.I'll be cheking my fuel preasure and my timing tomorow and I'll post results.

Ok my timing clocked buy timing gun was at 5 degrees.Is that good or bad.No vacume leak,no exhaust leak.

when usay u start it up...u mean cold start over night and it lags for a second...cause then when it warms up it doesnt do it right???

if it doesnt do it whern its warmed up..then thats normal...ur engine is cold it hasnt heated up yet...the combustion chambers are too cold to fire that fast....

let it warm up...ur suppose to anyways

another thing...if it does do it when its warrmed up...its something to do with intake
throttle body?
leak?
pipes?


anything to do with intake
