ok, about 2 weeks ago my truck started running poorly at idle. now it is all the time, like a loss of power. the SES light comes and goes, and i cant check the code with the code scanner i have because it dissapears when the truck is off and i cant check the code while thr truck is running.

anyway, my brother said it might be the TPS, i have taken that off and it looks almost new inside. im not sure how it works, but it looks like it is in good condition.

also, i am in bad need of a new pipe from the cat concerter out the back. i need to replace the gasket and the entire pipe (straight pipe) but i cannot find the gasket anywhere, do i have to take it to a professional or does anyone know where to find it?

When was the last time you did a tune-up (complete)?

bout 3 months ago, i drove my truck for bout 80 miles the other day and the problem went away....but the SES light still comers and goes...*shrug*
