You trying to tell me something then

[rbfisher]

I have a V8 flapper air flow meter ECU which I am selling. Let me know if you are interested.

Your car sounds like it is overfuelling which would indicate that the ECU is not well and is pulsing the injectors for too long or holding them constantly open.

Cheers,

The best way to diagnose - is to swap with a mates
who's is running OK.

You will know pretty instantly and if you fit
you ecu to his car - the symptoms who move to
that car !

Lucas 're-conditioned' ecu = about 200 pounds

A duff ECU can cause this but so can duff temp sensor, sticky fuel injectors, sticky thermotime switches for the cold start injector to name but three.

Where is the temp sensor situated when I find it I can test it.I am not a mechanic at all but can do things when told how to do them.
Any help would be appreciated as I want to bring the car to Duxford

Buy yerself a Rover SD1 Haynes manual,its all in there at the Supplementary info section. Saved me a fortune when my 390 cut out.
Using the Fuel injection troubleshooting guide i discovered my temperature sensor(for the ECU not the temp guage) had gone T*ts-up and the resistance was well out of range (you need a fairly good quality multimeter for this.)hence the ECU didnt know how hot the engine was and just threw up its hands in dismay!
Have to say though, it didnt give the symtoms you describe.
Mine was erratically cutting out after a cold start for some time ,but ok when warm.Then one day it just cut out and wouldnt restart whilst warm.
Hope this helps

Looks as if the ECU is the problem just had it sent away for a test.Anybody know what they do with them to get it back in condition.

My ECU was riddled with dry joints, very simple to sort if you are handy with a soldering iron, or knwo someone that is.

Hello,

My car, a 1987 350i, has recently been doing the same sort of stuff. When warm it just won't tickover without stalling. Every junction I come to I have to keep the throttle press slightly to stop the car from embarassingly cutting out. The other day I adjusted the idle speed with the screw on the plenium intake to increase the tickover speed. This worked for a few about half a day before the car went back to its old ways.

The car has also suffered badly from pinking too, and I recently experienced a short phaze where the car would just instantly cut out when sitting at tickover on my driveway. All leads me to believe that my ECU could be shot.

Call me stupid, but I take it the ECU is that box of tricks in the passenger foot well. I will remove it and take a soldering iron to it and let you know how I get on! You never know...

Daniel.

Something else you might want to check is your throttle pot. You can just disconnect it to see if the idling improves. My cold running improved significantly when I "refurbished" mine.
