new to the board and in need of help..
howdy all & thanks in advance for your advice:
so i installed the tms chip in my 94 325is the other day...
first day: car acts like its running out of gas and then stalls. starts right back up and i drive off with no problem.
3 days later: car stalls again - this time after a few high rev's. repeats this behavior 3 times or so, then starts back up and drives off fine.
whats up? could this be my o2 sensor?
My car has just over 100K miles.
