Service Engine Soon - 1997 Chevy Suburban

Asked by May 11, 2015 at 07:19 AM about the 1997 Chevrolet Suburban C1500

Question type: Maintenance & Repair

So I am having trouble trying to figure out
what to do. My 97 Suburban (1500 LS)
keeps giving me a service engine soon
light. One day it just started, and my step
father checked the codes. It was basically
multiple misfires. And the O2 sensor. I
replaced all plugs, plug wires, rotor and
cap. Seemed to fix the issue. But now.... I
am getting service engine soon light again,
checked codes and it is only one now
saying cylinder 4 is misfiring. Pulled the
plug, and it was all dirty and corroded.
Cleaned it with a wire brush, reset light by
disconnecting the battery and that seemed
to fix it. BUT NOW........ Same light... No
vacuum leaks. No oil leaks from what I can
tell. I'm screwed..... Need to fix so I can
smog it!!

It could be valve seals or worn valve guides letting in oil and fouling the plug, or an intake gasket failure, especially if the intake gaskets have never been replaced.

Worn engine components, as mentioned above, can repeatedly foul out a spark plug on a single cylinder. Try using a spark plug anti-fouler on cylinder #4. Basically the anti-fouler screws into the head then the spark plug screws into the anti- fouler. The anti-fouler shields the spark plug's electrode and keeps it from fouling out. Your local auto parts store will have them. HTH. - Jim

is the service engine soon light the same as a check engine light?

Jay, on what type of vehicle? Some had a service engine light that was just a maintenance reminder light, while others it was a light for trouble codes in the engine management system.

I have a same problems with my 1997 Chevy Suburban 2500 4wheel drive. Service engine soon light, on and off. Check engine soon light, on and off.
