Could a cracked manifold cause the motor to stumble at higher RPMS? I have been having a problem for a bit now and it caused my jeep to die on me the other day. I will be driving and when it gets to about 3800 RPMs it will do a fast pop pop pop and sound like it is mis firing or hitting a rev limiter. I was messing with the TPS adjusting it and it got worse a little bit and it would do a little pop at 2500 RPMs but then go all the way to 3800 and then do the same thing. I tried new injectors and nothing changed. When it died on me it sputtered and then died like it wasnt getting gas and then i had no fuel pressure. I could hear the pump kick on but wasnt getting any fuel. I took my lines off and blew them out with compressed air. After that i got good pressure again. But still no change. Now when i drive it i will get a sputter a little after i take off from a stop at about 2000 RPMs and it will ocasionally die. I have been trying to figure this out the entire week and nothing has helped.
