fast idle problem

I've been trying to chase down a P1188 code problem and today replaced the hose from the oil seperator (PCV) to the intake tube. I removed the throttle body from intake then put it all back together and now the car has a really fast idle. 1500-1800 rpm. occasionally it'll settle down to 1000 or so but it normally idles at 700-750. I've checked all the throttle and choke cables and nothing is binding. all vaccum lines are good and in place. not sure what to try next. any suggestions?

Perhaps you maybe put the cables back on wrong/backwards. Also perhaps you did something to the tbps.

Did you replace the gasket for the tb?

Idk... I would just retrace your steps, and see where you went wrong. Also, have you rechecked your codes? Are you now getting any codes for maf?

i did retrace my steps twice and found the problem but it wasn't anything I would have suspected. the cruise control cable on the tb had come out of the sleeve down at the tb and when i remounted the cruise control it was stretching the cable and giving it just a bit of gas. i figured it out when i had the engine running and disconnected the cruise control and moved it out of the way and the engine throttled down to reg idle. reseated it and secured it and it's running like top. go figure. thx again for the help!

No problem! I'm glad you found it. I knew it would be something simple. A lot of times I think we all get tunnel vision as we go through those final steps to complete a job.

Great job though... Hi5

thx for the encouragement! still chasing down a persistent p1188 code problem thats really got me stumped. I've read just about every post on two bimmer forums about this problem and the solutions are all over the map, and I think I've checked just about every one of them. thx again
