Thanks Salty, I had a test run. I was told I had two weak but not failed front 02 sensors. I was also told that there was carbon build up as the air is pushed across the cylinder heads and that was more than like the cause of my problem. A error code of po104 comes up. I can reset it and it will stay off while I do 100's of hiway miles but comes back on once I am back in the city. I was given an estimate of $4500.00 to repair. I was told by several others this dignosis was wrong. I read other forums and the fuel regulator was suggested. I do know there are times when the auto runs like new then suddenly the miss when at idle and the hard start. Any suggestions or ideas would be welcome.

Thanks,
MBD
