Is this a MAF malfunction?
I would like to seek your feedback on the following:
Alfa 166 V6 3l year 2000, the enngine idel was bit rough till it wormed up and the RPM stabilized at 900 (AR recommends 700 +- 50). few weeks back the injector signal was activated once or twice, it then disappeared, therefore I did add fuel injector cleaner to the tank.
For the last few days the inejctor signal remains on after starting for approx 10 minutes, then it goes off but then the RPM would reset at 1500 - 2000 (at N position); after few minutes the injector signal will come on again and the RPM resets to the 900 value. With the signal on the engine is a bit slugish while it seems ok when the it goes off. I am suspecting a faulty MAF and would appreciate feedback from those who expereinced similar behavior before taking the car for a check/tuning at R.
