Having problems with your 1999 Oldsmobile Silhouette ?
The problem i am having is that the motor has a knock sound to it. If i drive the motor smooths out and the check engine light flashes. As i let off the accel., it stays smooth until the rpm's get low again. When i park the car and put it in park, the check engine light stays solid. I plugged into it and got a code p0303. Cyl. 3 missfire. I pulled the coils out and bracket as well as the alt. i pulled the #3 plug and found it gapped at 62 with no electroyd left and plug is burnt. i pulled cyl. #
