ihateallmustangs Posted January 19, 2007 Report Posted January 19, 2007 Acutally this has been happening for awile but never bothered me much before but I want to fix it. The throttle on my car is really snappy (im guessing all 3.1 cars are like this). Sometimes when I hit the gas on stop and go traffic the car hesitates for a moment and then "kicks in". Almost feeling like its going to stall. I notice the volt goes down a bit and the dash lights ,etc dim. Today I noticed when I came to a hard stop the dash lights went dim again and my stereo kinda blurred out and came back on. I noticed small power surges in the lighting ever since it got cold ,etc. I have a small amp and a 10inch sub (not much power really). If that matters. I replaced the starter on this car for no reason this summer since the car had so many miles and I didnt want to get stuck changeing it in the winter just in case haha . The battery is about 3 years old and the alt was a used one I had laying around. Any Ideas? its almost like the car chokes for a moment and kicks in. If that makes sense Quote
mra32 Posted January 19, 2007 Report Posted January 19, 2007 I have the same stutter on my 91 3.1. I'm guessing its the IAC. Quote
ns87 Posted January 20, 2007 Report Posted January 20, 2007 Same on my car. I think its a vacuum leak somewhere... if you hit the gas just right it doesn't stutter for me Quote

Andrew Posted January 20, 2007 Report Posted January 20, 2007 how about the TPS? ive heard they can flat spot.... and i would have the charging system checked. cut rate will do this for free, probably other places too, but thats the closest place for me. they just put a volts meter on the battery to see if the alt is puttin out enough juice.

If I can find that sweet spot it will respond normal I have that also, it's like it doesn't move for a slpit second. I amgonna get new IAC and TPS anyways. Quote
