bump!!

Also wanted to throw my issues in here as well Seems to be related. I got a 94 Del Sol. 57K Miles. It ws sitting for 2 years when I bought it back in Dec.

When I first got it, I hard some start up and idle problems, had to hold the gas for 5 minutes before it would idle on its own. That went away after using the car for 2 weeks. (I guessed the IAC was lil stuck form sitting) Fast forward now to last week.

Wife let the car run down to almost E, it started sputtering bad on startup (cool car), and idled better as it got hot. I ended up changing the fuel filter (is was nastier than nasty with rust-oxiude). Also changed plug wires and rotor, I hadnt done that since picking up the car.

The car starts fine (coold) and idles erratically, kinda like a plug is dead. From a stop it stumbles bad, until I get over 2200RPM then the car moves.

I have verified I get good solid spark. (timing could be off, need to get a gun), but I wanted to know if this could be a fueling issue? Or more towards that IAC valve?
Again, only happens at IDLE, and below 2.2K.
