Hi all, I just had my oil changed and to make a long story short, they left the cap off, and it sprayed oil everywhere, they cleaned it up, but now the car misses under any type of acceleration. I can feel through the gas pedal exactly where it feels like it changes something in the throttle, this is exactly when it starts to miss, no backfire or anytijng, just like a dead cylinder. any ideas?
Depending on how much oil leaked out it could of gotten down to where the spark plug is and causing it to short out if the oil is in the spark plug boot. They also could of crakced the breather hose that comes off the valve cover while they were cleaning it.
99.9% of the time a miss under acceleration and not at idle is spark going where it's not supposed to. If they cleaned your motor good chance they hosed your car down with engine degreaser and water to clean it, pull your spark plug boots and I'll be willing to bet they are wet. Wipe and blow off the wires and blow out the plug wire holes completely with compressed air make sure everything is dry.
BTW. Do it one at a time so you don't lose the order...
ok, that sounds like an idea, I will dig into it tuesday and report back what I find, I belive they are under the BMW emblem strip form what I saw yesterday.
And, yes, I did see them out there with a hose...
