Engine Stalling+ FIXED!!!-Read First Post
My engine is stalling at idle, usually when I'm stopping at a traffic light and my foot is off the accelerator. Can it be the idle actuator? Anyone else have/had this problem?
I want to be sure it's the actuator before I purchase a new one. No trusty alfa mechanics or EFI technicians around here, they want to charge me 50 bills just to take a look at the car. I'd rather spend it on the new part.
Quite frankly it's driving me nuts and it's also dangerous having your car stop in the middle of traffic. Other drivers must think I'm dumb and can't drive.
Finally found out part of the problem that was causing the stalling. My mechanic and me thought it was the step-step motor (U$S 80.00), but before I made the purchase, we exchanged it with one from an other 33 with less km, and to our surprise, while it did help, it wasn't fixed. We then started to get ready to clean the MAP sensor just when it happened...fuel started coming out through the vacuum hose the connects the fuel pressure regulator to the intake manifold. Turns out that the regulator had a broken diaphragm and fuel was pooring into the manifold through the vacuum hose. The engine flooded somethimes at start up and was jerking hard on gear changes. What a diference, it feels like a new engine. But it still stalls once in while, usually when warm, at about 50°. Before I changed the regulator, it stalled every time I stopped, or lifted my foot of the accelerator. I am now inclined to think that what ever stalling is left is probably caused by a faulty temp. sensor. According the the owners manual, the ECU reads this sensor among others to keep the idle constant.
I'll keep you posted with any news.
