BMW Repair Questions? Ask a Mechanic for Answers ASAP
hi, I have a bmw 316ti, 2002 e46, with an m42 engine, it misfires on 2,3, and four cylinders, have had it in 2 garages and has cost me £750 so far, but no remedy to the problem, when I drive on the motorway and go above 45mph it seems to run smooth, please help.
what exactly has been done and tested?
Timing chain has been replaced, injectors been replaced, ecu been bench tested and it seems to be fine.
sorry for the delay
why was the timing chain replaced for a few misfires?
