Weird Throttle

[Passatie]

I have owned a e36 1999 for about 2 weeks now and notice that when i accelerate gradually everything is fine but when i plant the throttle into the floor the car seems to take ages to do anything then when it does its kinda slow and jerky. I changed from a turbo motor so thought it was just me not getting the kick from the turbo but the more i drive it the more im convinced there is a problem


any ideas such as realigning the throttle, are they DBW or cable or any known faults with the accelerators ?????????

i need you to explain a bit more about your car and car history, such as is it auto? was this car turbo , or a previous car, mileage etc etc.

I think he is sayign that he used to own a turbo vehicle and that nwo that he has this car he is a bit cautious.

How long does it take to kick in? A second? A few seconds?

Auto or stick?

Sorry guys, its a M3 1999, 62000 miles, manual and it drags its ass up to speed when you floor it. If you gradually accelerate its really nice and powerful and you get there faster than if you floor itused:

hmmm something i noticed with my car as well, it seems to respond to a gradual use of the gas pedal (aggressive but gradual) than just stomping on it, however i pass it off as a mind trick, maybe you could have something wrong with the car, its hard to tell as an armchaim mechanic... do you feel the power is responsive and adequate when in normal use?

[Passatie]

under normal driving the car just pulls and pulls and keeps going but stomping or fast throttle movement the car just does not want to know, it seems like it over fuels but the is no smell associated with over or unburnt fuel ?

No offense but possibly its the way your drivin it..downshift, then stomp on it all the way to 7K... if your stomping on it in 2nd or 3rd gear at 2500 rpm it will lag..just a thought..

62,000 is a little early for this, but I've seen it once before at low milage:clogged catalytic converter, or for that matter any other restriction in the exhaust path. If you have the ability to check your CAT temperature (ie infrared thermometer) while the car is running, it should be fairly constant front to back. If it's blazing hot at the front end and cool at the back, there's your problem.

speaking of exhausts this one has a stupid loud thing attached. the back box has been changed for a universal back box by the previous owner and its so loud it gets on your nerves even at 40mph. Could this be a problem, lack of back pressure etc
