I think im going to take the spark plugs out and see if there fouled. I have allready pressure tested the coolant system to see if im losing coolant to the piston, or oil and im not. so i think im going to take it to the shop to put it on the diagnosic machine. The test I ran was though the check engine light. (dont know how effective that is)

Listen

Did you calibrate your TPS sensor????? The TPS is not just something that you just screw back thorttle body.
