The car has been absolutely a joy to drive. Obviously, she's getting a little old & tired so I expect some things to start wearing out & they are. However, one of the biggest mysteries lately has been the malfunction indicator light.

Starts fine, cold or warm; runs great with no misses or hesitation. After driving for about 10 minutes or 20 minutes, the indicator light comes on. Manual states that it is an electrical problem. After the light comes on, the car starts cutting out for a brief moment. Runs good, cuts out, light goes out, light comes back on in a few minutes, sometimes stays off, etc. After driving for whatever odd minutes, I'll be stopped in traffic & car dies. It's flooded. I push gas pedal all the way to the floor, crank it a few times, then she starts. It's ok after that for most of the time. But sometimes the indicator light will come on again & start the whole process over.

If I can get this figured out, I'm sure she'll last a few more miles. Dad used to do all my troubleshooting, but since he moved out of state, I'm not exactly a mechanic & I would appreciate any specific help. Thanks.

Well first, there about 30 different 'codes' that could be present since the indicator light is on. You will have to get the car to a dealer and have the problem solved. Your best case is to take it to a Mazda dealer. Alot of times some shops will miss diagnose certain codes on vehicles.

Personally it sounds like you may have a MAF sensor issue or a coolant temp sensor malfunction. But that is just a guess by your discription of the problem.

Thanks for the info Cosmo, let alone the quick response. I'll research what exactly MAF sensor is, but I'll mention it to the dealer once I find one.

I wasn't aware they could hook-up a computer diagnostic with that old of a vehicle. I'll keep in touch. Again, thanks.
