service engine soon light
 

I've been driving my zr-1 as a commuter this week. My wife wrecked her car a couple of weeks ago and the z is my option since she is using my truck. Anyway, I am not complaining.

I am driving 40 miles each way on mostly freeways with very little traffic lights. Also this week has been mostly in the rain. I noticed my service engine soon light come on while crusing at 65 mph in 5th gear at @ 1800 rpm. This stayed on for about 2 minutes then went off again. About ten minutes later, it did the same thing.

This has reapeated itself each day on my commute. The light never stays on and does not come on at startup other than its usual routine with all the other lights.

Any ideas guys?

has the car backfired recently?

Get your trusty paperclip out and see if any codes are setting. Has the idle changed (Higher?)

While it could be several things, start with the simplest first. Try putting in a full tank of quality gas like Mobil premium. While I never put in off brand gas in the ZR-1, I have in other vehicles, and almost every time I get an intermittent check/service engine light.

First thing to do is check for codes. :iamwithst. Forgive me GC. We need just an "I agree" emoticon.

Nope no backfires that I have heard. Doesn't seem to idle higher but I will pay attention to that more. Going to find my paperclip. Thanx guys.

Yep, I am stupid with this stuff.

Also,

I only use shell premium gas 93 octane. Never used anything else in it! Would thier "nitrogen enriched" crap, affect anything?
