Question M44--> RPMs take LONG to drop down after Blipping the Throttle....

I'm buying a 97 318i sedan (w/M44 engine) in just a few hours. One thing I know I need to fix/adjust is this.

When you "blip" the throttle, the engine RPMs seem to hang-up and don't drop immediately. I know 16-Valved engines loved to be revved, but the RPMs "should" drop off right as soon as the throttle is let off.

Other than this issue, the engine performs flawlessly.

Past experience tells me that this is a throttle body/butterfly setting.

If it is, how do I adjust it properly.

you don't... if u suspect the butterfly, what u need is a can of carb cleaner or brake cleaner and spray it with gusto to take out all the gunk that is in there ;-)

a "hanging" throttle can also be a binding linkage. You'll need a body to flick your throttle so u can see what the linkage or cable does.

...or a faulty TPS is also possible.

Thanks for the quick reply.

That actually makes sense since the throttle pedal feels "funny" to me (kinda hard like the floor mat is stuck under it....but it's not).

The engine is Not as responsive as I'd expect. I know the M44 is a dog (performance-wise), but the engine "should" respond (and decelerate) much quicker than it currently does.
