(sorry spilled my drink) driving my car it bogs, no acceleration, lost of power. dealership found nothing wrong, but just cleaned the sensers, maf,iac,and reprogrammed the ecu to it's specs. threw a bottle of BK or BG fuel system cleaner, and the celi ran as it was brand new. after 1/2 an hour of driving it started to loose pick up in 1st and 2nd gears, bogs down until i hit about 3000 rpm. the power kicks in. brought back to the dealership 2 more times, and they did exactly the same procedure as the 1st. Has anybody had this problem? if so, what did you do to fix it?
