1998 GMC Sierra V8 Four Wheel Drive Automatic 186000 miles
I'm trying to pass California Smog tests. I have passed all the tests except the MIL/Check Engine Light test. 1st time I went the check engine light was on so I disconnected the battery to reset it. I was told I needed to trive my truck 40 miles or so to reset the monitor testing so I did took it back and was told it still hadn't reset, so I was driving some more and now my check engine light is back on.
I am at a loss of what to do.
have the same problem?
