Hello all, i am brand new to the board as well as brand new to BMW's. I just bought a 91 735I and i am having some trouble. When i bought it it needed a few little things.
I changed the spark plugs, air filter, and oil.
the car was running great now it has no power and takes 20 minutes to get to 60mph. the only thing i have changed is i put 2 tires on the rear (225-50-15) the fronts are 225-60-15. i was the idiot that went and bought tires and didnt remember the right size. i didnt notice untill i mounted them (in my garage) that they were a different size. the traction control light came on as soon i took it out for a drive and i now have to turn the traction off. But the car is still real slow. i can floor it and it wont get out of its own way.
No lights on the dash are on, no check engine light,no EML, no nothing. its just slow. i am going to put the new tires on the front and i am hoping that with doing that it will take care of the traction control light.
any help would be great. i love this car but i dont think i was ready for the the hassles of owning such a great car.
