I have a b16. the cars runs great when i drive it when it is not wamed up. when its warmed up it runs like crap...the engine has jerks when i try to accelarate below the vtec mark. What engine componenets could be causing this?

 

Bad TPS

 

Possibly the ECT sensor, try bleeding your coolant system of any air. An air bubble or low coolant level in the system can cause these sorts of issues when the car is warmed up.

 

alright thanks guys ill try all this and see if it all goes away.
