why is my jeep doing this???????


Recommended Posts

To me, it sounds like clogged exhaust or dirty injectors/fuel filter. The engine wants to stall out, which is why it keeps revving up to keep itself running. Replace the fuel filter to be safe. They're cheap anyways. There's tests that can be done to test your exhaust. I've seen someone drill small holes in the exhaust before and after the catalytic converter to measure back pressure (you should get nearly the same number in both spots if it's fine). A clogged cat would explain the o2 codes. Another thing you should do is check all the plugs of the sensors you replaced and make sure they're clean. You can spray WD-40 in the plug and then blow it out with an air compressor to clean it out. Try doing that on as many plugs as possible. No one can really tell you the exact cause of the problem. It's more of a trial and error process and we have to go through your work (and assume it's done correctly) to single out the problem!

EDIT: Also try putting some injector cleaner or seafoam in your gas tank

Fuel pressure regulator is built into the filter on the vehicle so i wouldn't go saying they are cheap. That isnt your typical $10 fuel filter. More like 40-50.

What he needs to do is find a good driveabilty guy in town and take it to them. All the money you are wasting just throwing parts at it could have already done paid to fix the real problem if you hadnt just been guessing.

And FYI. Just because its throwing an O2 code that doesnt mean the sensor is bad. Shorted wires in the circuit in the harness can cause those codes too.

You guys act like you have never clogged a toilet and ran around the bathroom frantically hoping it don't overflow.

BTW, Wix part number on the fuel filter is 33929 if you feel like continuing to just throw parts at it although with it being a little more complex than just a filter, i would suggest getting an OE part. . I'd personally be taking a real close look at the crank position sensor.

Did you try cleaning the throttle body? Sounds very possible that it could also be a vacuum leak somewhere.

yeah i cleaned the tb. and checked for vacuum leaks by inspecting all of the hoses nd fitting were tight

if it was a clogged fuel filter then it would run like that at all times would it'?>

Hey, I'm just guessing here like you are currently since i don't have the car in front of me hooked up to my $10k lab scope to pin point circuits. Driveabilty issues aren't a guessing game, there's a science to it to find the actual problem which is why i told you to take it to a shop.

i had a remanufactured one sent with all updaded programming and it did the same thing. my wire harness was touching the exhaust manifold and starting to melt wires, i secured that and it seems to run alot smoother lol idk this american junk is making me wonder why i ever traded my integra for it lol
