first off, i drive a 95 eclipse gs 420a motor.

two nights ago my car just shut down on me. while i was pulling over to the side i tried to down shift and it did but i couldnt gas it..my lights and radio still worked..so when i was stuck on the side of the road i started up my car again and it would start up but die out after 5 to 10sec.. when i towed my car home i started it up and it would start and run good, after a while of driving it would happen again shut off and have a hard time staying on..would anyone know whats wrong with my car???

i did the key dance thing to have a little self diagnostic check..these are the code that came up

12-airflow sensor fault
36-oxygen (o2) sensor fault
21-coolant tmp sensor fault
55-idle air control (iac) valve position sensor fault

would they be the problem why my car is acting theway it is???

 

As redundant as the title of this thread is... (lol)
55, 12 and maybe 21 are not good, man. But 55 and 12 are most likely why your car doesnt want to run.

 

This question sounds familiar.
12 actually means that the battery was removed within the last 50 cycles.
55 actually means end of codes.
Look in the manual, those two aren't codes from the manual at all.

 

Here's what the book reads..
21 - Problem with oxygen sensor signal circuit. Voltage not fluctuating....it should be.
36 - Open or shorted condition detected in the secondary air injection solenoid (manual tranny only).

So, you have an issue with the o2 sensor and your emissions equipment is going or is bad.

All of which have no bearing on the battery light. That is a charging issue. BTW, those codes will pop up if those sensors aren't supplied correct voltage...hint, hint.

 

Im still debating if youre good at making deductions or you just spend too much time in the garage haha

 

Lol, I'm always asking myself what each and every thing under the hood does. I'll look at all my books and research and I eventually figure it out, one way or another

 

thanks slivercoupe97..i got the code information on google..i guess i was wrong..so how do i fix the problem??

 

Nah, not you bro. Google just grabbed the wrong definitions.

 

Here's what I would do...since you have a 95, I would go ahead and swap out the old ASD relay and change out the crank angle sensor. They react to heat as magnets do. Without the crank sensor signal, thecar will die because the ECU no longer "knows" where the crank is in it's rotation, just like it would if there's no cam angle detection. That's how the ECU knows when to fire the plugs.

 

Is the engine grounded? PROPERLY?
