Exclamation random stuttering at 3000 rpms

i tried to search for this problem, but i have no idea what its called so sorry if its a repost... in my 95 talon, about 50% of the time my car will not let me accelerate past 3000 rpms with the clutch engaged or disengaged... the needle just bounces around 3000... sometimes if i shut the car off and back on it wont do it, then other times it does do it... im still a beginner and trying to learn but id really like some input before possibly getting raped by another mechanic

Re: random stuttering at 3000 rpms

thats what it sounds like. Which means it must be some sort of ecu cut happening. (LIke a stutterbox) I'm not saying it has to be the ecu though. You could be getting a weak signal somewhere causing the fuel to cut when a certain voltage is reached. My friend had something similar I'm going to ask him what it was on his 300M that caused it. (Damn Chrysler)

Re: random stuttering at 3000 rpms

Im willing to bet you have a real bad boost leak somwhere.. do a boost leak test.. ..also could be your mas airflow sensor....just for shits and giggles try unplugging it and rev it up slowly in nuetral .. see if it will let u get past the 3k..

Re: random stuttering at 3000 rpms

Def. sounds like the ecu to me. Although it could be bad distributor, jsut a suggestion. The MAF would probably throw a light on.....um....relays and fuses?

His car isin't turbo and doesn't have a MAF sensor. It has a MAP sensor on the manifold. It doesn't have a distributor either, electronic ignition.

This is a very odd problem, I would think it would either have to be a sensor bad or the ECU. If a sensor was bad it should throw a CEL. Do you know anyone that might have an ECU you could swap with just to rule that out?

Re: random stuttering at 3000 rpms

Fuck me! LOL, yeah the ignition coil should be checked. I would also check to see if you might have some oil in your spark plugs.
