Question about 1989 Honda Prelude
The car runs rough and idles high then low runs rough when first started then it starts the high and low idle
I had the same problem on a Rover. There was a leak in inlet manifold that was caussing the problem.
To verify, spray some sealant to temporarily seal the inlet manifold .and the eratic idling should disappear for some time.
If it does, you know there is leak in inlet manifold which you can take of and refit with a new gasket.
