DOC... do you Know of...
a "quick n easy" way to test air mass sensor or the fuel pressure regulator?
It happened a couple of times few weeks ago that the tachometer needle was dipping below the 500 rpm mark during traffic-light stop and dtc19 would come on the next time i start the car... but that hasn't happened after i resetted the adaptation as I described above... it beats me! Now everything looks normal and the car drives great. Needle sets at about 500 rpm during stop while in gear and about 550 when in neutral. I am diffenetly keeping an eye on it and will be looking for testing few components that may cause fuel delivery problems... Thanks in advance for any pointers..
