86 525e
 

Please help me:cry
the 525e has developed a bad miss on acceleration to the point now where its just stops and wont go.

have replaced coil, leads, plugs, distributor, fuel filter and pump, computer, 2 sensors at gearbox/engine, air flow sensor.
as the car warms up from cold it misses and stops and wont go again.
seems it looses spark as it warms up.
had this now for three weeks and no one can help me- except you guys, please.

check ignition wiring harness (not plug wires) it sounds like you have a wire(s) when they get warm the expand and lose contact. Use an ohm-meter to test wires after it warms up. Also check your ICV, they gum up and cause similar symptoms as you described. Dudesky did a fantastic DIY about it : http://www.unitedbimmer.com/forums/t...?highlight=ICV
