I was using this thread to parallel and rule things out....he said he thought a spacer would help[, i have the spacer he was talking about using, VERY helpfull to people and him and me too... to see that a change like that will not help his situation, ruled that out.... he could use one BUT it will not cure his problem..... ALSO it is funny you say to start my own thread.... WELLif I were to do that ... i would have been told to go to this thread.....if you cant see the value of two engines/cars with the SAME idle issue side by side with varying options to help rule things out... you are misguided...
