I have a 1992 charade with just over 200 000 k's on the clock. i was driving the other night and the check engine light came on then turned off again, then a couple minutes later it happened again.
i read the manual and it says that the light is the engine control system, what is this likely to be that is causing the problem? my ECU or something else?

Re: Check engine light
Your Engine check light is part of the onboard Management/diagnostics, each time it lights a fault is recorded in the Computor,(OBD) it may just be a service interval reminder?
I recommend taking it to a competant Technician and ask him if he is capable of OBD checking and clearing? You may need to have a few jobs done but if the vehicle hasn't given you problems then possibly just a routine service is required.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Firing Order: 1 - 2 - 3 Base Ignition Timing Note: With the T terminal Shorted.5 +/- 2 deg BTDC Ignition timing should be checked and adjusted, if necessary whenever spark plugs are replaced or any distributormaintenance is done. Ignition timing should be 3-7°BTDC at 750-850 RPM with the engine check connector terminal 11 (brown) shorted, Fig. 1. The engine check connector is located near the top of the transaxle.
These problems are always frustrating. Some of the charades swicth directly via the stalk on the column, while others have interposing relays. A common problem with dimmed headlights, indicators and dash lamps on the charade is caused by the fuse box retaining screws becoming loose .... these screws are also the -ve path back to the battery via the chassis.
If you have a meter, check voltages between the fuses and various metal parts to see if you can suss out a poor continuity path. Check your chassis strap between the battery -ve and the body is clean and tight.
If the car runs fine until it warms up, then the check engine light goes on and it all goes to hell (sputtering, dying, etc...) then it is most likely the o2 sensor. Take it to autozone and have them put it on the scanner, just be sure to bring it when the check engine light is ON.
