Like i've already said in the past i have a really rough ride when the car is cold in the morning if it hasn't warmed up. (hesitation and really jerky acceleration). After the temperature guage gets up to where it should be for driving all those problems are gone. Some people have mentioned in the past that it may be the over head temp sensor or something along those lines? correct me if im wrong?

 

cylinder head temp sensor. Here is a writeup.

 

Thank you =)
