Is it possible to have problems with TPS and not get a code? Seems like there is a certain throttle position gives a hesitation and bucking around 20 mph noticable at all temeratures of engine. Nothing dramatic, just a small amount.

Mine was a little bit out so it never registered that I was idling, but there was no codes when I was driving. I never got around to see if I got a code with the diagnostics connectors jumped though. After I adjusted it and put the throttle body back on, the check engine light started blinking, but that was just because I forgot to connect the TPS. :pat:

 

just make sure you have a cover sheet on our TPS report

 

mine has come completely unplugged before and all it did was miss slightly at idle, the check engine light never came on
