I got a 1991 Convertible, this light came on the other day while I was driving home from school. It goes on and off though... Usually it'll stay off for the first twenty minutes of driving, and then it'll slowly blink, and then finally stay steady. However, it only stays steady when the gas isn't pressed. It will always remain off during acceleration and it'll slightly blink inbetween shifts. However, whenever the gas isn't being pressed, it stays on. If I put the slightest pressure on the gas pedal in any gear, even in neutral, it'll go off.

Recently I changed the O2 sensor, air filter, spark plugs and spark cables. It's been about three weeks since those changes. However about a week ago my dad tried to fix the idle problem it's been having, it's been dying during the first 10 minutes of driving alot on hot days.

Any idea what the problem could be and/or how to fix it? Any help would be greatly appreciated. Thanks.

Okay I got three different numbers here: 12, 13, and 31. So that's the throttle sensor, pressure sensor, and solenoid relief valve. Any advice? Would I be able to get these parts checked out/looked at like at a Pep Boys, or would I have to go to a dealership? I also wouldn't mind installing the parts myself if that's possible, I'd like to learn as much as I can about my car, I'd need a guide though. =/ Thanks for the help, it's much appreciated!!

Sorry for the bump, but looking for help. ^^;;

if you know how to use a multimeter and have the Haynes manual or FSM, you can read out the sensors in question before and after the CEL is on, & compare the readings...either that, or kill the ECU's memory by disconnecting the battery for a while, then immediately check the code for the number the first time the light comes back on...
