I have a 91 Ford Probe GL. I've had it for about three years. All of a
sudden it's gotten where it wont idle, but runs just fine.
A neighbor who is pretty good working on cars thought he knew what it
was and replaced (don't know what you call it) a dryer hose looking
thing from the air cleaner. That didn't fix it and he looked pretty hard
for a couple days for "air leaks" and found none. He said it may
electrical. Is there something electrical that controls the idle?
He also found maybe related? He showed me he pulled all the wires off
each spark plug and the idle changed except on number1. The spark plug
is getting spark. How do you check to see if a injector is bad, or could
this be something else?
I can't afford to take this to the shop at this time.
Never mind him... you posted in the right place.
You say it "runs good".. does it seem to accelerate "rough"?
What engine speed (RPM)does it smooth out?
I had somewhat the same problem and it turned out it was the plug wire
Suggest you try new plugs and wires, .
A cheap way of testing is to switch the #1 and #2 plug wires on both ends and
see if the position of "no change" moves to # 2.
Bear in mind the plug could ALSO be fouled
