1997 Eclipse Spyder GS with P0505 code.
Hello,
I recently purchased a 1997 Sypder GS this month .. The IAC and ECU were replaced by a Mistubishi dealership (HUB Mitsubishi) in March. The previous owner then unloaded the car to a dealership. Well, the car looks good and I decided to purchased it.. Now to my problem ...
I have the CEL on and my basic ODB-II scanner shows a P0505 - IAC Malfunction. However, when I cleared the code, it did not appear until the engine warmed up to 189+ degrees, then the random idle started. When I talked to the Mitsubishi shop mgr, he stated there might have been a cooling system issue when they had the car but could not give me any more information. I was wondering if anybody here could shed some light on where I need to look to try and resolve this issue.. Apparently there has been a couple of auto shops that atempted to repair it before they ( an Auto Shop) actually took it to the Mitsubishi Dealership to get it repaired ... Any assistance would be greatly appreciated ..... With the IAC and ECU so recently replaced, I am leaning toward something else as the real issue.
My car:
1997 Eclipse Spyder - Kalapana Black with Tan interior.
92K miles
2.4L SOHC
5-Spd Manual
and a lot of fun to drive !
Best Regards,
Danny

Usually that code is the ISC motor needing to be replaced. Otherwise, maybe check the throttle body. Take it out and clean it. Might even be a leak in the throttle seals, or check the throttle cable itself
