Engine Performance problem
1996 Chevy Tahoe V8 Four Wheel Drive Automatic 200500 miles
I have a rough running engine. I had the diagnostic run on it 3 times (clearing the comp each time) in the past 9 months. Each time it says no# 6 cyl not firing and the o2 sensor is bad. I replaced all plugs, wires, cap, rotor button. It still reads no#6 miss when the tester is hooked up. The miss does not seem to be all the time. Only noticeable at idle (sometimes) and going up hills. It also says o2 sensor is bad. How many o2 sensors are there on my 96 tahoe. And would the bad o2 sensor only affect 1 cylinder. Also what is the injection spider.
have the same problem?
