B23F Rough Idle 200 1983

posted by  someone claiming to be cdcrawford on  Wed Jul 19 13:12 CST 2017 [RELATED]

Thanks for the suggestions, guys.

About 5 years ago I had a surging problem that ended up being the hall sensor in the distributor. But in the process of chasing that down, I replaced the IAC, FPR and coolant temp sensor. The accordion hose was also replaced at some point.

Wondering if this could be caused by uneven compression due to a HG leak? I seem to have to top off the expansion tank every 3-4 days and there is no obvious leak. I've also noticed the temp gauge (there is no compensation board on an '83) sometimes goes up and then comes back down at idle. The motor is original and 34 years/400,000 miles old so I wouldn't be shocked. Then again, it pulls hard enough to "bark" the tires in 2nd which would be rather odd if compression is low.
