My 2.0 had the FI unceremoneously removed by a previous owner and a cheap no-name 2 barrel mounted in its place. It has been running OK but yesterday when I first cranked it, it did not want to idle. I was going to take it to run a few errands so I figured I had not been driving it enough lately so I took it anyway. Once it warmed up, it wanted to "idle" at about 4 grand. I could stab at the loud pedal and it made no difference, still 4 grand. I got it home and let it sit a while and cranked it again, same thing, 4 grand.

Today, I sprayed the carb full of carb cleaner and let it sit a few minutes, not it wants to idle at 2 grand. Any ideas, suggestions, names of good hit men, etc?

Thanks,
Mike

sounds like a vacuum leak.

Have to ask..... have you looked at the t'rottle return spring? (and general state of the cable)

If it's a leak, it usually repeats the same symptom, then get's worse.

take off the filter top. open the throttle plates let go, they SHOULD snap back to close. bind in cable, stiff/ hard to operate shaft?

I misunderstood the original post. That probably is a vacuum leak - and a big one, too!

Vacuum is likely it, dang thing doesn't have a vacuum hose on it that's not in pieces.
