My car problem started when I ran out of gas at a plaza.
I did something stupid, by putting into the empty tank “Octane Booster” hoping it’d get me to the end of the plaza where there was a gas station.
Well, it got there (although it was knocking and idling very very roughly and acceleration was almost out.
Well, filled her up, and started her, but as soon as I hit the gas pedal, the acceleration would nearly die, and power goes way down and engine light came on!
One thing I noticed, I had to pull over for 15 min. cause my headers got too hot (red hot) and I could smell them! I had to let them cool, then started the car, then minutes later , same problem!
I don’t know how to interpret what the ECU is trying to tell me, and I really can’t afford the $100 charge to diagnose it. Plus why is the exhaust so hot, causing the headers to glow???
You’ve got the 91 ECU, with the car off, turn the key to the “On” possision but do not start the car. On the passenger side of the car where the passengers feet go, pull that part of the carpet back and you’ll see your ECU. There is a little round window with an LED in it. When you turn your car “On” the LED will blink.
It will blink fast and slow. 3 fast blinks and 2 slow blinks woiuld be ECU Code 32.
I just did it and found out it’s Code 14 (I am pretty sure it’s not 4 because there’s a quick blink immediately after I turn the ignition on. But the repeated blinks are the slow four ones! So i assume it is 14)
Well Code 14 stands for “Idle control system” But I don’t know what part is broken or is messed up. What should I do next? Does it simply mean I need to check an idle control valve, or what?
sorry it took so long for me to answer but the code 14 is a problem with the electronic air control valve (eacv) circuit.
The EACU changes the amount of air bypassing the throttle body in response to a current signal from the ECU in order to maintain the proper idle speed.
im gonna try my best o explain to you where its located work with me:
up under the intake manifold on the drivers side. dircetly under it is a metal plate with hoses going downward. there should be a connection there (in front) of the eacv. make sure its tight. the only way to clear this code is either replace eacv,make sure the wires are tight or change out he ecu. this is all according to the fctory manual. if you got anymore ?'s let me know. hth
