Engine & Tuning
Got an e46 325ci which is dropping revs. Example. I'm in 4th or 5th at about 3,500rpm (50-55mph) and when I accelerate the revs jump to about 4,750-5000rpm and then drops back to 4,500rpm before the power kicks in.
It might be the MAF but I am unsure that I need to replace this as it...
