Engine Performance problem
1997 BMW Z3 4 cyl Two Wheel Drive Manual 48000 miles
This is my first post here. My car is a 1997 BMW Z3 1.9L 4cyl M/T. With 50,000 kms
Im experiencing stalling/misfiring during high speeds or high rpm usually when I hit the 180kph or when nearing rpm redline. The car sounded like starving for fuel/power. I dont have "check engine light". But when I turn off the engine and start it again after a few seconds, engine will run fine again. Runs fine in idle and everything seems okay if I limit my speed maybe up to 160kph or around 5000-5300 rpm.
I already changed the fuel filter and sparkplugs. Fuel pump seems okay. No problems during start ups and idle. I only experienced stalling/misfiring during high speed/high rpm but no check engine light.
What else could be the problem?
Thanks and hoping you can help me.
have the same problem?
