I have to reset my check engine light for an inspection and when they hook it up a lot of things still show incomplete. How many miles do you have to put on it after reset for it to calculate everything and say its alright so it will pass inspection? I sure do miss the days when this wasn't a problem. I forget computers are running the show now.

I think you have to drive about 75 miles or so or have a few cold to hot run cycles before it is OK. What was the trouble code in the first place?

There has to be a number of cold start to warm cycles before it will indicate properly for inspection. Just driving around won't do it.

Cylinder 3 was misfiring, but I replaced all the spark plugs and fixed it. Thank you for the knowledge, I was told it was just about the milage. Had no clue it was cold starts as well. Thanks again!!
