I own a 316i, 1999model. when I put my foot down on the gas pedal sharply, The rev counter will not show over 4000 rpm, but if I gradually increase the speed it will show max. rpm. But in practise, the car will not pick up speed, when a sharp acceleration is needed! Please tell me what to look for. It felt if there is a starvation of fuel. i have a 1993 318i, the engine misfires badly once i go to 4500rpm and loses all power, i have changed the filters, plugs and leads but it is no better! once i let off the throttle it eventually clears and runs fine, any help please! I have the same problem in my 2001 bmw 325i it wont rev past 4000 rpm
I'm having this same issue with my 91 legacy turbo. NO ability to accelerate hard and can't rev past 4300 in neutral I've changed the pump checked vacuums. Checked filter. I'm at a loss....
Take it to a mechanic to check the timing. if the timing is off then it may run at a idle an a little above but once you rev it up then the timing will truely show an it will run like ****. have you checked your air filter that may be another cause. hope this helps
Sounds like a fuel filter issue. If the filter is clogged or is getting to the point where it's going to be clogged badly the amount of fuel going to the engine will be restricted. This would cause your stated problem. Theoretically there isn't much of a need to go over 4000 rpm unless you are racing with the car but I think most bimmer owners can understand where you are coming from:) As far as the 1993, I'd check all your intake piping and vacuum lines and make sure there are no leaks whatsoever. An easy way to check is to have the car running and spray carb cleaner on the intake piping and such and see if your revs increase, if they do you've got a leak. Hope this helps! I'd be glad to help with any other questions you might have a please don't forget to rate me.
