Stuttering between 1000-1700 rpm
While driving my wife's 97 the last few weeks I have noticed some brief stuttering right when I pull away from a stop. Just a real quick hesitation and it pulls fine after that. It almost feels like a missfire. Power seems normal and it pulls just fine all the way to redline with no additional missing or popping or anything. During normal cruzing above 2000rpm it runs fine (no reason to cruise below that in any case).
I checked the plugs real quick after work yesterday and they looked on the hot side with a white electrode. No indication of knock, but it looks a little on the lean or hot side of ideal. It had only a little carbon deposits just above the threads, so no major carbon deposits from a lot of missfiring or running rich. I checked all plug wires and everything looks OK. The wires were replaced less than 10k miles ago.
If I bog it down in higher gears I can get it to stutter between 1200-1700 rpm and then it picks up fine. It is only under load because if I free rev it in nuetral it runs just fine.
Over the last two weeks it is gradually getting a little worse, not bad yet, but I am a little concerned since this one is my daily right now untill the 91 turbo install is done and tested.
