what to expect from cam swap
Greetings all,
I just swapped out the stock M cam for a K cam in my B230F. Everything went back together nice, double checked the timing belt marks. When i started it up, the ignition timing was off by at least 20-30 degrees. After I set the ignition timing, it is idling nicely, maybe a little fast. First drive, it diesels just off idle, like it is knocking for a second, then goes fine. So, question is: does the fuel injection (LH2.1) need to re-learn the new cam? Anything else that could cause this? I bought the car recently and someone else had replaced the belt before I got it. Could they have had it a tooth off and changed the ignition timing? It was kind of doggy before.
