I have a bmw 325e the car runs good cold, when it warms up it runs sluggish,then when I turn it off and wait about 5 min turn it on it has no power sluggish, can't carry itself 10feet, it's a 5 speed car. I've changed the motronic control unit , the mass aitflow, the cts, checked the exhaust for blckage, to no avail, any ideas help

This may have already been done but should be inspected:

This Service Information Bulletin supersedes S.I. 13 07 84 (854).
It lists the production date (1/85) of vehicles with the modified idle control unit.
SUBJECT: POOR INITIAL DRIVEABILITY - "HOT ENGINE" WITH A/C ON
MODELS: 325e
VEHICLES PRODUCED PRIOR TO 1/85
Complaint: Poor initial driveability may occur on 2.7 liter engine equipped vehicles after restarting a "hot engine" (coolant temperature between 105 to 140 degrees F) at ambient temperatures above 68 degrees F with the air conditioning ON.
Correction: If any of these conditions occur, proceed as follows:
1. Disconnect idle control unit plug.
2. Unsnap plug cover.
3. Remove brown/red wire from Pin #11
4. Insulate wire connector and tape back against wiring harness.
5. Reconnect idle control idle plug.

See if that helps and let us know.
