Drax240z Posted August 9, 2003 Share Posted August 9, 2003 Ever since I've got my car on the road, I've had a slight miss every once in a while. This occurs at idle, and light throttle for sure, and I'm fairly certain at larger throttle openings as well. It corresponds with a very short lean out on my mixture meter. You can feel the hiccup through the whole car as well when it happens. A slight lurch to the car. (though rpm's seem to stay stable) I've tried adjusting the TPS, as it was suggested to me the part throttle could be due to a porrly adjusted TPS. No dice. There are no "holes" in my EFI programming that would account for this either. I had a notion that I might have an exhaust leak and am running too rich, so I'm getting a small amount of combustion in the header or downpipe. This could mess up the O2 sensor signal I would think. Thoughts? Ideas appreciated. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 10, 2003 Author Share Posted August 10, 2003 *bump* Anyone with some info for me, especially on the possibility of this being an exhaust leak? All 6 plugs look good, tan-to-black colour. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted August 13, 2003 Share Posted August 13, 2003 the only thing i could think of is if one of your injectors might be bad? I had a miss in my NA eng. and it was cause of a bad injector. But if you say your sparkplugs look good i dont know. : one thing my mechanic told me to do to help find the problem is to run to napa and but this fuel system cleaner called SEA FOAM. this stuff rules! Even gives you better gas mialege and stuff . Fred Hope i could help wish you the best of luck Quote Link to comment Share on other sites More sharing options...
Guest comeandzpa Posted August 13, 2003 Share Posted August 13, 2003 check your plug wires, both at the plug and at the cap. That's what the problem was when I had the same problem Quote Link to comment Share on other sites More sharing options...
