ok got a Idle Air Control Valve and put it in today and it still bucks at a hill climb until you press more into the gas then it smooths out. abit of a rough idle also. now i have not tested the new used part yet since i have been sick ass a dog . took pretty much took all had today to change it out today. but will do it soon. how i tested since i don't have a tester harness is have someone turn the car on not the motor just the key and see it moves or adjusts. the other did not or just barely after cleaning it. have not on this one. so i guess i am asking if this part works out ideas on where to look next.
