Vehicle in question: 91 Honda CRX DX Well, I searched for IAC and TPS related posts but could not find anything that seemed to lend a clue as to what might be the issue I'm having. This past Fri. afternoon/evening leaving work start the car all is well, get about 0.1 miles down the road engine light comes on. At idle it idles like shit almost doesn't register on the tack, probably idling ~ 500rpm. Although give it some gas and the car seems to accelerate fine. Get home after all of a 4 mile drive turn the car off, wait a moment start the car again all is well, no check engine light etc.... parked for the weekend. This morning the same symptoms occurred. A note to add whether it's a coincidence or not but the air temperature here in CT has not been about 35 deg F for a while now. I need to check the engine code but can't remember were the connector is or which pin to short so I can get the code. Any and all help would be appreciated.
