Hestitaion?!??!?
Ok i'm running into a small little problem. I jus installed the pcmforless chip I ordered and just got. So I installed it and test drove it and it worked out fine but then the next morning came around and im lettin the car warm up and it starts to die cause of the cold start injector delete so i go to push the gas and nothing happens for a couple seconds and then then rpms go up so i pulsed the rpms for a while till it got steady. then through out the day when i would shift into both 1st and 2nd gear i would push on the gas and it would hestitate badly but 3rd 4th and 5th were all good no hesitation or anything. my thought is with the MAF i deleted the screens and it got a lil bit better but still a hestitation. wat do u guys think? do they make a bigger MAF for out cars? where can i buy one? Thanks for all the help

Re: Hestitaion?!??!?
A similiar situation has happened to me. I was running a tune for about three weeks, then as I was getting ready to take it out and scan it, the car started running rough. It happened literally while it was sitting in the drive warming up.

I'm thinking it is something else other than the tune. Just cannot get over the coincidence it happened as I was setting up diagnostic equipment to scan the car.

How did you determine you had no spark?

When i had the car running with the chip in and i started to pull the wire off and then i put it back on one at a time on the dist. cap and saw and heard no spark occuring. but i then took my chip out and it ran a thousand times better so it was my chip that was givin me the problems
