your oil pumps probably going bad
if you follow Jeeps recommended gap the knock sensor activates and it knocks. Just gap to .060 - 075 " and make sure to have plug cap bar on correct. so knock disappears. WTF
not a timing issue since the iron duke 2.5 engine has no timing belt
It sounds like a vacuum problem. Either you got a bad brake booster or the vacuum line came loose somewhere or cracked when you changed the booster.
worship used to be bad before now the Prophet Muhammad came it all changed first people worshiped idols were drunk and worship fire but now that changed
They used to be bad but now they're good.
i just changed my batterys out on my truck now my check engine light is on?
if fluid is black in color it is burnt and do not survice rebuild or replace. if brown it is ok to survice. As far a goes bad it is like shooting craps
The coil pack you changed for that cyl. may be burning build up in the cyl. and may clear soon, or the coil pack may have been shorted to hide the fact that cyl. was a oil burner, now its live and burning oil once again
Was the truck running OK before the plugs were changed?If ok before the plugs were changed then I would recheck the plug gap & check the plug wires. It is easy to damage the carbon fiber inside the wires. If they are old say around 40.000 miles I would change them. If truck was running rough before plugs were changed I would look at timing & vaccuum. Also cap & rotor. The converter can be a problem with rough engine perform. Check for bad gas.
Bad coil? Bad distributor rotor? Bad ignition pickup? Bad distributor cap?
In line filters are directional. check that filter was not installed backwards look for arrow on the side of filter. arrow should point towards engine an away from fuel tank
