Rpms not dropping

Not to insult your intelligence, but have you checked the pedal to see if it's sticking? Is your floor mat jammed up next to it?

Sometimes, the most obvious things are overlooked. Since you didn't mention you checked these things, I thought I'd mention them.

No offense taken. But i have no floor mats and i pulled on the pedal to see if it made a difference and no difference.

I had a similar problem after taking my throttle body off. Turned out just to be the throttle cable being too tight holding the butterfly open a tad. Just had to adjust it back so that the throttle could actually close again and all was fine.

This was obviously on a car with no e-gas though....

Bentley Boxster Service Manual, page 24-6:

DME adaptation for throttle unit can be done if these conditions exist:

vehicle stationary, battery > 10 V and < 16V, engine temp >5C and <100C, and
intake air temp >10C and < 100C

if the above are true then:
1. switch on ignition for 1 minute w/o starting engine

2. switch off ignition for > 10 sec


now see if it's fixed (pray...)

cool i will try this in the morning and hope it does the trick

[gikser]

Well adaptation didnt do the trick. Curiously enough the car idles perfectly fine at a standstill so it only happens when driving mostly on the highway. Im stumped.

Bump. Anyone has any clue?
