Umm, try to switch/check out your coolant temp sensor (not the temp sending unit) and/or the intake air temp sensor. Sounds like it has something related to the cold start operations of your vehicle. If your sensors are out of range, it could very well cause the rough idle/hesitation until the operating temperature increases.

 

actually my problem starts after it reaches operating temp. before that its perfect.

 

Oh, well that sounds like the TPS to me. Did you test it and make sure it's set at the right angle?

 

gotta get a volt meter today to set it....
what are the specs for the tps?
aint they like 0.5 closed and 4.5 full throttle????
