I have the same problem 200

Hmmm... I have the exact same symptoms om my 88 240.

It seems like the ECU thinks that the idle is too low and keeps trying to raise it. But I'm not yet sure why. I was thinking maybe the tach input isnt getting to the ECU but I haven't checked that yet. Or the ECU could be bad itself I guess, but somehow I don't think so.

If you figure anything out let me know. I'll do the same for you.
