Ultrafinder Posted May 22, 2008 Share Posted May 22, 2008 This is also posted on AC, for the people that only post here I have almost gone section 8 with this problem. I need some help. First I have a 1994 SE with 230,000 mi.. Last year my truck would miss (stutter) a little while idling w/ air cond and only happens after warm-up. Not too bad happened maybe 1 or 2 times a week. That lasted a few months then it started to happen more frequently to all the time with a/c on. I band-aided it by turning the a/c off at lights. The problem progressed to stuttering whether a/c was on or not at idle. Now the stuttering is so bad it almost stalls and when I am just cruising down the road it stutters. I replaced the timing belt just in case and it didnt help. So over a year it progressively got worse to the point I can't drive it any more. I had a preemie baby 5 mos. ago and he is finally coming home next week and I need my truck bad...This what I have done so far. I changed the O2 about a year ago which I have recently unplugged to see if the stutter goes away and it didn't. I changed the plugs, rotor, cap and air filter about 6 mos ago. For good measure I changed the cap and rotor again yesterday, no help. Also changed fuel filter. I have a FSM and changed the temp. sensor this morning which didn't help. I cleaned and tested the MAF, it's good. I checked and rechecked for air leaks and couldn’t find any. Finally, I waited for last and changed the IACV which wasn't cheap, that didn't help either. I also did the Sea Foam thing. I can't figure out why this happens only after warm-up and there is this loud popping noise coming from behind the motor every time the idle stutters almost like an elect. arcing sound. It's not the 6 plug wire or the fuel regulator. I have a stethoscope for just these times and as close as I could get to the sound it seemed to be coming from right around the back injector. I can't tell if the drop in idle is causing the sound or the sound is causing the drop in idle. As you see, I have run out of things to check and it's getting expensive changing parts. I don't know if this helps but the gauges are starting to act a little funny too. If you have some ideas I could sure use them. Link to comment Share on other sites More sharing options...
