I would run some engine diagnostic tests to determine if it is an engine problem. Then I would aim to look at the transmission system. This also involves looking into the transmission's computer. You need to take it to a shop that has a scan tool that can scan the transmission control system. A lot of the BMW have advanved logic in the computer and the average shop will not have the tool. You will probably have to take it to a bimmer dealer.

I have a 2002 Celica GT 5-Speed and I shift at about 4k RPMs when getting on the highway and I still feel I'm accelerating to slow. Am i doing something wrong?


Not driving a corvette? Just kidding. More details are important. How slow is your acceleration? Is it 0-60 in 8 seconds, or 20 seconds? What is redline on your car? If redline is 5K then 4000 is a good responsible shift point. If redline is 8K then shifting at 4000 is probably robbing your engine of it's torque and horsepower band. I believe the GTS model has an 8K RPM redline, the GT may be lower, but in that case, shifting at 4K is too soon for strong acceleration. Your Tachometer should have redline clearly marked. For responsible use, stay below that, maybe 10-20%. For economy stay further still, but for power you need to let the engine use it's RPMS, especially smaller and fewer cylinder engines usually don't make their power until they are half way through the RPM range and above.

I have a 1994 325i conv. the temp gauge cycles between normal operating temp and overheating as i'm driving.a few minutes in each range.could it be the radiator.blocked passages? is this common to older...


my 528i does, or did the same thing. Overheating is bad for those aluminum cylinder heads. 1st, replace the coolant. Then check to see if the electric cooling fans work, or cycle on, they most certainly would have to cycle on when the temp gauge is in the red zone.
1st thing most people do is replace the thermostat. However, if the temp goes from overheating to not overheating in less than a minute, the thermostat is working. The key thing to look for is why did it get to the red zone in the first place.

2002 Civic EX wont accelerate


It sounds like a problem with the transmission. The creaking could be a bad power steering pump or simply a dry/leaking rack & pinion.

Hello.

That doesn't sound right, I'd suggest getting the spoeedo checked. Even if you had the close ratio gear box which I think was fitted to the 4 cylinder engines, your speedo should be showing 160 km/h at 5000rpm in 5th.
