Comming back from service..now i have problem.

GOTHP · 11-19-2010, 06:03 AM

my oil change was due, i visited dealer today

they replaced my air filter, spark plug, engine oil...under warranty..

came back to my home, and when i parked, and i realized the car was shuddling and idling rpm below 1k..

it doesnt seem to settle, it keeps up/down 200/300 rpm

From my knowledge, I believe this is lpfp??

I test drove the car, no limp mode, no long crank, car runs like it should be..

I havent noticed this before dealer visit tho...

Advice needed.

Its possible you have an injector that's malfunctioning. I just took mine in for the HPFP, car comes to the front for me to get in it and its smoking like a freight train. Tech discovers its the #3 injector thats inoperable, needless to say he was not pleased because the day before the car ran beautifully.
