    OK everybody...add this to the growing list of troubles:
    The engine seems like its missing at speed...it only will do it under some load though, and it seems to be alot worse when the engine is cold, like during the first 10 minutes of running in the morning. It will lurch and skip five or six times, then smooth out, then do it again. It was just tuned up last summer, I run nothing but Mobil 93 octane, new TPS last summer..what is it then? Its a stock 89...350 tbi. Any suggestions will be appreciated.
