Thanks for the info I will try all of that. It has 90xxxbeen miles on it. And does have a slight knock but only when coming down from a higher rpm . The knock I can deal with for now. Its the performance that's frustrating. I was also told that a knock sensor could cause this but I can't find one and its not in the error codes. Oh and the sensor looked perfect just like the new one.




Update

Changed the crankshaft sensor and it looked a bit rough but didn't fix it. It does idle lower now about 750having rpm.
