Ok! I think my ALFA needs Dr. House.
1- Yesterday night I removed the air filter and gave it a little clean (vacuum cleaner) - just to let you know. (I had to remove the first section of the pipe, that connects to the MAF) Didn't take the car for a ride.
2- Today I tried the "throttle reset" I went for a spin. At first it seemed like it was a little better. But the symptoms were still there.
3- Stopped the car and engine for some 5 to 10 min. Disconnected MAF plug. Took the car for a test drive.
Perfect idle and car running perfectly.
Darn!!!! IT's the MAF! I thought!
4- Stopped the car and engine. Just the time to reconnect the MAF.
The idle needed some seconds to adjust to 1000RPM. It steattled!
Test drive the car again. Perfect running just like WITHOUT the MAF. It can´t be! Did I connect the plug right??Or I'm I still running without MAF?!
5- Stopped at a gas station. Engine Stopped!
Gently verified the plug - It was in did correctly connected.
6- Started the car, and off I went again.
It seemed fine, still!...
... No!...The symptoms are still there after all! What the hell?!?
7 - Stopped the car immediately during the "coughing"!
Engine off. Just the time to unplug the MAF again!
OK!!!! Now it seemed the MAF was really OFF. No stabble iddle. The engine strugles to keep idle between 750 and 500RPM.
The symptoms seem all to be there, on top of the poor idling. Car is difficult to drive in traffic.
8- Almost getting home, I stopped the car to reconnect the Plug.
Again, normal idle settles in in a few seconds.
The rest of the ride, one block only, was uneventful. But I'm sure the symptoms are still there.
So, wirering, right?
My mechanic's best guess was "spark plugs" or (don't now the word in english) "the energy coil thingy" that's responsible to give energy to the spark plugs"
Do you concur, Dr.s?
PS- By the way. Yesterday, with all the symptoms showing quite intensively while crusing on scenic road - had to keep RPM over 2000 - I entered the highway.
No symptoms there - Reached 180km/h (110mile/h) quiet easily!
Just to make that point perfectly clear!
