From there the idle sort of "bucks". Soon it becomes such a "buck" that it stalls the car. I have an E-303 cam and i know someone mentioned that they are notorious for that problem.
Now that i know the problem is only in "Open Loop" operation, is there anything i can eliminate right off the bat as i try to trouble shoot?
It can't be a vaccum leak or it would happen in both open and closed loop, correct? |
I might be
loopie (well, we know that), but I think you have your loops backwards.
OL is when O2's are not used (Cold motor, WOT, etc).
CL is when the motor is warmed up a little and O2's are used.
I wanted to make this distinction - people who reply would probably want clarification. good luck.
