last night, my car started to die on me when almost everytime i change gears. the service code i pulled out was p1348, p1346, p1344, p1342 which are cylinder 1-4 misfires. this morning when i started up the car, it was acting wierd as heck. The rpm would rev up and down and the car would shake a little as if it's having hard time breathing. And then as soon as i shift out of Park, the car dies. could it be as simple as a tune up? please help!!!!!
Make/model? My misfires happened after performing a hotsoak, where I dumped cleaner directly into the intake manifold. Any chance you have a leak in a vacuum or intake line to the manifold? Have you cleaned the fuel injectors recently? If it happens when you shift gears, I wonder if it's not because of a brief lack of fuel delivery...
2001 bmw 330Ci auto. Last week I use a bottle of fuel injector cleaner when i was filling up. The car idled roughly this morning. I don't know if there is a vacum leak or not. Keep in mind once i get the car going, it drives normal. I've read other posts, they suggest that my Idle control valve might be faulty. This sucks a** because there is only one independent shop that will look at bmw's within 200 miles here. I appreciate all the help
Agree with Dirty Tool. Do you get a whining noise at certain RPM's? If so, you probably have a vacuum leak... check your air intake boot (two rubber pieces). If not, I'm still sticking with something related to fuel.
