Yeah, I know.
So to start off, my Jeep has been functioning terribly over the past year or so.
It's had an ongoing issue where it won't idle and I have to apply gas + brake at the same time to keep it alive, which I thought was from a clog in the catalytic converter.
I want to say that there was some kind of clog in the intake manifold instead. Here's why. On cylinder #1, before I drilled holes, today I found a couple of cracks in the manifold which looked exactly like they had been created *by* vacuum pressure itself. There had been a leak and large enough vacuum pressure from the cylinder to actually pull straight through the plastic at it's weakest areas.
So I figured, well ok let's see what happens when I drilled a hole right there. Just where those cracks we're at.
Sure enough, my car now idles like new.
Now all I have to do is figure out what's going on with the engine. Just this morning, before drilling, the car developed a consistent "hitting" sound louder at low rpms that is same as the speed of the engine. Mechanical hitting sound, like something bad. Piston hitting something or some kind of mechanical issue w/ explosions opposing engine momentum.
Anybody have any idea what could be the cause? Sometimes during acceleration the pop will occur louder at times, like something randomly hitting something else harder. Definitely sounds... bad. It is completely consistent, does not "disappear".
(Edit: Also, I don't think it's possible anything got into the cylinders through the cracks - the first ones were way too small for anything to get in there)
