So I am going down the freeway doing about 70 and my engine chugged for a second and then was fine. It did this randomly for the drive if I was @ 70. But if I cruise @ 55. no chug. It's like the fuel cuts out and then comes back. Shouldn't be the fuel pump that thing is only a month old. Also could the fact that I have 33's and no new speedo gear be screwing the computer up? :confused:

Maybe I should throw a 350 in there eh? Hows aboot that?

When was the last time you changed fuel filter?

The filters are on the pump itself which I changed a month ago. Oh yeah in the investigation process I found a hose cracked that went from the tank to the some lines that looked like it went to the brake mast cylinder. Anyone have an idea what what's all about?

i had a similar problem with my yj... it turned out to be a set of wires had fallen onto the exhaust pipe. when the wires got hot enough, the coupler would liquify, and make the jeep sputter, and lose power. a minute later, when it hardened again... it would run fine.
i went through this all the way home from the rubicon to lakewood.
it was a very looong ride.
there is something else for you to look for. :wave:

Do you carry a spare CPS? Might want to start (should already be in your spares box anyway)

I will have to check some wires this weekend. I changed out the CPS about 5 months ago. Wonder if it went bad already. I'll throw both those on my things to check. Thanks for the info :D

CPS shouldn't go bad again for quite some time. Don't know on the TJ's - but I do know late model YJ 4.0's have a problem with eating coils. I carry a spare :)
