Agreed. The IAC too. (Idle Air Controller). This can get jammed with tiny
amounts of deposits. I would probably use carburetor cleaner.

When our 88 does that, I pull off the electrical plug to the TPS and
give it a spray with contact cleaner then am usually good to go for a
year or more before it needs it again. Electronic contact cleaner is
the best, but WD40 will work.

That works every time on ours.

I've tried cleaning the contacts on the ISS and TPS with electrical contact
cleaner and a toothbrush, with no change. Forgot to mention that.

I'm thinking it may not be too easy to haul the throttle body off, but I'd
imagine that would make it much easier to clean properly?
