Re: P 0303-uh oh

To be sure the problem is speed related or rpm related, just put the transmission in 2nd and see if you still get the problem at 40 mph. If not, just check if it occurs at the same rpm. I would be surprised if it would be speed related.
The engine doesn't make more mechanical noise when the problem starts?

Re: P 0303-uh oh

Yo Frango ... I too would be surprised if it were speed related but I can certainly buy it being RPM related. Nonetheless to confirm or refute that possibility I'll try the 2nd gear/RPM thing. There is no remarkable engine noise when the trigger trips; it just runs rough as you would expect with only five banging away. I'll get that LiveData from the reader and put it up as a PDF. Won't be till tomorrow at the earliest.

I guess I can't say specifically for a jeep vehicle but I know for a fact GM vehicles function that way...

OK, the LiveData is here:

http://www.writingplaces.com/ftp/200...an12262012.pdf

as a 3.8 mbyte PDF file. The first frame is the trigger frame.

Putting the Heep in 2nd, I found that the code tripped at about 3500 RPM, at just over 40 mph.

In Drive, it tripped at a much lower RPM, but at the same MPH point. So, it does in fact seem to be linked to MPH rather than RPM.

Update guys:brought my WJ to an independent guy in the Chicagoland area(MBS Automotive, the owner is awesome and they have extremely fair prices). Got the steering realigned, and the fuel injector that was misfiring got an insulator. Problem is fixed completely, it still idles a little strangely, but not anything like it was before. Somehow, my terrible average gas mileage before has somehow(miraculously!) increased from 11.4 mpg to 18.2!! Awesome!

Next order of business for me will be getting a little more power into the puppy, z

Bought a K&N drop in air filter today, not expecting much, if anything to change. Just a fun, simple little mod. Why not.

While I'm at it, is it worth it cleaning the entire airbox out? I took out the old air filter yesterday for inspection and it looked sort of dusty in there.

Always good to clean, the dust in there is what the air filter took out of the airflow, it otherwise would have ended inside the engine.
