Alright this may have already been answered previously but, today in the morning I was driving to school to take a test and when I was going from 2nd to 3rd around 3.5k rpms the car suddenly starting losing power immediately as the rpms started to drop. I took the car to the side of the road and it turned off, when I turned it on the first time the brake, and cel were on, no vdc or slip lights. Immediately after it turned on it turned off if I didn't give it gas. This happened around 3 times until it finally started keeping power and was able to go to class. After the test I was able to get home w/ out any problems. No lights on whatsoever.
Recently I changed my cats to resonated test pipes and I did not do a idle relearn reset, I am wondering if doing an idle relearn will solve my problem, any input is helpful.
