So car ran and drive fine up until the check engine light, it idled fine, hit the gas and died. Tried to start it right back up and crank crank crank and nothing. Waited a minute, wiggled some wires, tried again crank crank crank nothing. Went to auto zone bought the innova ford obd 1 scanner, checked it with the car not running, just ignition turned to on, hit on and test. First go around gave me the 15 & 85 followed by 11. I got back in and cranked it, boom she is running like normal no more check engine light. 10-15 minutes later while running the check engine pops back on, car is idling hit the gas and off it goes. Tried to crank it right away and just crank crank crank no go. Ok replug the scanner same 15,85, 67 since I guess I didn’t have the clutch engaged and 66. Checked the mass air, seemed fine, plug was tight, unplugged and replugged it. Waited about 15/20 minutes tried to start it and on it goes no more check engine light, head home as soon as I pull up to the drive way, check engine light again and hit the gas and it dies again. Parked it, came out later the evening and it starts right up, running fine, put it in the garage. Started it up yesterday and it cranks right up, no check engine light on at this time. I have no idea what it could be. As far as clearing the codes like described above no I have not tried that.When the engine quits, will it restart immediately?
Have you cleared the codes to make sure you aren't seeing old codes?
How to clear codes.
Clearing the codes by pressing a button on the scan tool or disconnecting the test jumper used to start the code dump does not erase the “learned settings”. All it does is erase the stored codes in memory.
You must clear the codes anytime you replace any sensor. The following tells you how and is different from the method above
Clear the computer codes by disconnecting the battery negative terminal and turn the headlights on. Turn the headlights off and reconnect the all sensors including the MAF and anything else you may have disconnected. Then reconnect the battery negative cable.. This clears all spurious codes may have been generated while troubleshooting problems. It also clears the adaptive settings that the computer "learns" as it operates. Clearing the codes does not fix the code problems, it just gives you a clean slate to start recording what the computer sees happening.
Run the car for at least 30 minutes of driving and dump the codes again to assure that you have fixed the code problem or sensor problem. This is necessary for the computer to relearn the adaptive settings that the computer uses for proper operation. The engine may run rough at first, but should smooth out as it runs for the 15-20 minute learning period.
