Engine Performance problem
1994 Saturn SL1 4 cyl Front Wheel Drive Manual 179000 miles
First Im not sure if I have a saturn sl 1 or sl 2. How do I find out? OK here's the problem changed plugs wires checked coil packs and replaced O2 sensor. Now when I first start the car in cold weather it idles but is alittle rough but runs awesome (great pickup, really runs great) and as soon as it gets up to warm temp. (Within 5 min of starting) it begins to run terrible bad idle to the point of stalling and feel as though it is running on 2 cyl. The plugs get a lot of carbon deposit and black smoke when rev, high, so is my choke sticking? And which sensor is it, can I disconnect it and try running to make sure before I spend any money? Also there are no code when checked please give me some answers if possible idel goes up and down too about 1500 rpm then down to less than 100 and usally stalls out. Your thought. Thank you in advance
have the same problem?
