Hello from Spain!
Hi all, I come (if the site is not suitable Tell me), my name is Ismael I'm in Seville (southern Andalusia - Spain) and have 3 years a BMW 535i E34 (1991). Also I have a problem with it I can not find solution.
The problem is cold, cold start when you start your car idling is very irregular, if not accelerate and try to get out through the exhaust explodes after unsos seconds and doing well. I think it may be the wiring ...
Has proven anything but: flowmeter, lambda probe (it is new but not original, the disconnected and remains the same), fuel pressure regulator, idle valve and UCE
Sometimes also with warm engine speed and try not respond, going as drowned and hits a pull and suddenly goes well

Bad idle could be an intake air leak, disconnected hose etc.
A backfire through exhaust is almost always an electrical issue.
If it suddenly runs fine I would look for a bad or loose electrical connector.
Did this problem just start happening after the rebuild?

Vacuum hoses are all new, I think so, although I'm not sure because after 2 days to have it rebuilt it. I check the electrical connectors and cables running over the injectors. I think it may be electrical problem of the temperature sensor ...Originally Posted by 632 Regal

welcome Inmy, cant help u with the problem but nice looking car though
Many thanks, I have them all revised and new, all we have not seen is where it says' To the purge valve underneight the throttle ?? '' and the tube from the intake manifold ICV is not new
Today I received the electrical system that goes up injectors and apparently everything is correct, the temperature sensor wires are frayed. I have taped well, I leave the video for ye see him better
By the way I have just given me that I have two identical connectors. Agree that the canister valve. I have changed and then try them as the car goes, are both two pins, I have to check what color each wire carries. I only remember that one of them is yellow (you just put)
