 Cyliner Misfire Problem
Hey guys wassup im new to the forum. I just got my car last week, its a '96 318ti with an M44. My car has 170,000+. I also changed the spark plugs to Bosch Platinum Iridium's (are these ok?). As I was driving one day and came to a stop at a red light my idle started acting up...it droped from 900 to about 600 and was fluctuating in between. The check engine light came on and when i ran it on the OBD Scanner it said Cylinder 1-Misfire, Cylinder 2-Misfire...and so on until cylinder 4. I also hear a whistle from the motor at low RPM, but when applying a little bit of gas it goes away until the RPM drops again.
Plz Help Me! |
