So BMW 330i approx 123,000 miles. has been running rough at stop signs and idle. It either dies or wants to take off. So after reading codes it shows misfire and MAF sensor. So changed MAF, plugs, and coils. Still shows misfire on #5. Any ideas on what else it could be??
Looks like you just have injector to check/replace next.
Swap injectors with another cylinder. See if the fault travels with the injector. If it doesnt, time for a compression test.
