Catfish and Ramrod - you were correct on the MAP sensor, but since it had been replaced only 10,000 miles back, we skipped over that at first. Took the 'Chicken" to my friend's son who replaced the Mass Air Flow Sensor and checked the program.

After a couple of local trips, drove it to Watkins Glen last weekend (250 miles one way) for the auto races and it seemed to run fine. Lee had no explanation why the MAF sensor would go bad after only 15, 000 miles, but it only cost me about $225 for the sensor and another $200 prior to that or $425 all together (between the two garages), which included new platinum plugs, transmission flush, coolant flush and injector cleaning, plus the new (rebuilt) sensor.

Thanks for all of your help.

OOPS - I meant to thank Pakus for his comments about the MAF -sorry! No offense intended - none taken hopefully.

Still, thanks to everyone.

When replacing plugs I always recommend a set and the original type. Different type plugs of different materials (even with the same gap) fire in a different heat range - might be enough for computer snafu. If running lean use LOWER octane fuel for less temp and burn. Also keep in mind - carbon clogging the converter can foul stuff up. Where does the exhaust go on a high miles car with converters when the converters are clogged solid and blocking the pipe?
