Could one problem be leading to another???
so, heres some background first. I drive a 2006 MC LTZ (3.9L). A few weeks ago, I noticed that i could feel a moderate vibration while sitting at idle. This vibration got worse if the car was in park. On top of that, my tach fluctuates VERY slightly while at idle. First off i replaced the plugs, because i figured they had probably never been changed since new (i was right, they were ready to fall apart). This didnt change anything, so i started looking for vacuum leaks in the hoses (carb cleaner method), again...nothing. So FINALLY i looked a little deeper and found a small rear head gasket leak. I plan on doing a top end rebuild at the end of next month and hopefully that fixes it.
NOW, to the newest issue!!
While accelerating from a stop at idle (foot not on accelerator) the car is very...jumpy well call it. I mean i can feel it pulsing forward every other second. This jumping seems to match up with the rough idle sequence.
My question is this, Can a head gasket leak, which is essentially also a vacuum leak, cause this rough idle and give the car that lurching sensation?
My guess is yes, but im no certified mechanic, just a driveway wrench turner
Id love to hear y'alls opinions on this, and sorry for the long post
