nobody,s fixed my car yet. thanks for the responses but nothing so far i am paying attention,and searched the archives, found some similar proplems but no positive answers. had to get back on top of the board to refresh some interest.here it is again,still, in general the motor runs great.everything's new if it was questioned as trouble. at 2000rpm it breaks up and drops rpm,also at about 2600rpm the only time it dosn't is in park or neutral and you stomp the pedal to the metal. instant redline,smooth,sweet. i am starting to think its the car's brain and not mine i have done the typical tests and recomendations. new clue today i noticed the air temp on OBC is 122degs.??? is this the same info. brain is getting.how to fix? the problem is so consistent @2000rpm it must have been experenced before and solved. by the way my new call letters (bsandy) reflect my motorcycle flavor(BSA)and my business (BARNSTORM)but not my way of doing business. but right now some bs mixed in with some good info.would be acceptable thanks andy
