Idle Problems 99'
Hello, been having a strange problem for a few weeks where I am not getting any CEL, but when I am in gear stopped at a light the truck seems to bog down and then catch up and rev a little then idle back to normal. this doesn't happen every time i stop either only sometimes.
The other thing is that it seems to be running rich, smells like gas coming out the tailpipe when it idles.
Any help is appreciated,
Thanks

If you don't have a scan tool, take it to a parts store and ask them to scan it for codes and see if you get any clues. I'd be suspicious that the MAF and/or EGR might need cleaning but that's just speculation. The Mass Air Flow sensors on these especially are notorious for getting dirty and causing it to run/idle rough. Fortunately if that's the problem it's a cheap and easy job at least.
