Service Engine Light came on

Sep 29, 2003 13 Replies

I have a 1994 C1500 V6 with about 160,000 miles on it. It runs like a clock but my service engine light flicks on and off. Oil is ok.



I need to bring it to the shop but was hoping someone might be able to give a heads up to look for a certain problem.



Thanks in advance.


scan it for codes and let us know what you find

until we get some data, all we can do is guess from a distance

everyone know that they went to the bushing-style muffler in 1992 !

Yeah, but when you tighten that tranny belt you've gotta be sure and use a left-handed 5/8" wrench. A right-handed one doesn't fit past the Knuder valve.

If you had to guess and if you have not done any maintenance in forever, then there's a good chance that the O2 sensor/s are bad.
