I HAVE A 1984 BMW 533I WON,T START WHEN WARM AND IDLES TO HIGH WHEN IT IS STARTED. DID TUNEUP CHANGE THE FUEL PRESSURE REGULATOR, REPLACED THE IDLE CONTROL VALVE, THE COMPUTER STILL THE SAME IDLE ABOUT 1500 TO 1700 ON AVERAGE. STARTING IS A PROBLEM ALSO YOU CAN START IT ONCE DRIVE AND PARK IT WON'T START AGAIN FOR ABOUT 2 TO 3 HOURS, IF YOU TAKE THE BREATHER HOSE FROM THE VALVE COVER IT WILL START, IT'S ALMOST LIKE IT's CHOAKING IS SELF OUT. NOT ENOUGH AIR OR SOMTHING HELP...
