BigC Posted May 17, 2005 Share Posted May 17, 2005 I just purchased this car about 2 month ago and it stutters between ~1700-2500rpm. Sometimes it's hardly noticable, other times it will jerk the car, not violently but you can feel it definitely. It doesn't seem temp related. If I get past 3000, it pulls smooth to red line. On the low end it doesn't stutter either. It idles like a sewing machine..super smooth. It is most noticable in 2nd and 3rd when the engine is under load. There is no CEL on and car has 165k on it. I have replaced the following: - plugs - wires - PCV valve - fuel and air filter - crank and cam position sensors I have checked or done the following: - 1 bottle of techron (1st tankfull) - 1 can of seafoam (half into the intake, half in the gas tank, 2nd tankfull) - 2 bottles of heat (3rd tankfull) - Grounding kit, re-tourqed stock ground points - Resistance on fuel injectors is 11.4 ohm accross the coils on all 4 - EGR tested good, bogged engine when vacuum present - coil has no sign of deposits or corrosion...not saying it's not bad but.... I don't know how to pull OBDI codes or I would have done that. I did a lot of searches on this board and others and found a lot of suggestions for similar problems but no definitive answers. Sometimes folks don't post back though when they do have a solution The fuel economy is great, 28mpg avg. in three tank fulls and I'm not on the highway much. Obviously I feel like I'm down to all the expensive stuff. Coil, MAF, TPS or injectors. Sorry for the long post but I didn't wanna keep saying "I tried that". Thanks in advance for any input!
