OK I have three problems that have really been messing with me. First problem. The idle is really weird. Sometimes it will idle low sometimes it will idle high.(already cleaned the Iac nothing changed) As it warms up the idle will increase. Second problem it likes to linger in first gear once it gets into second gear it's fine. Third problem. The transmission will "buck" this will only happen when you barley have your foot the pedal just to keep speed, The equivalent to cruize control. Any and all help would be appreciated. I'm thinking tps but I'm not sure.

 

What's under the hood?

 

Need more info to help such as what has been done to engine up to this point, and has anything helped at all up to now.


Be aware that when replacing sensors that some should only be OEM because the failure rate of aftermarket ones are high, very high while others will do OK with an aftermarket one.


Crusier54 is the man on the "Renix" models, I'm sure he will chime in soon for better insight into your problems,

 

To my knowledge the engine was "rebuilt" about four thousand miles ago. Or so the previous owner says.the only thing I have done engine wise is a new water pump. I found one loose vacuum line and that helped a little bit.
