..at least I think they're fuel problems.
About a month ago the jeep started acting up and basically after it had been driven a bit in the morning, if you hit the gas, the vehicle would have intermittent power. It would be on the gas for 1 second, then the engine would cut out for one second, then back on for 1 second. It was like clockwork, it had a very defined frequency.
It did this at all speeds and all loads once it started.
Anyway, we replaced the fuel pump and the coil. Also did the fuel filter and cleaned the screen and pickup since they were pretty filthy. There weren't any codes on the engine and all the sensors behaved according to the diagnostics computer (had my mechanic check them)
Well, it acted fine for a couple of days and then it started doing it again. It's also developed a new trick - when you get below 1/8 of a tank the engine will cut out in turns.
I guess the replacement fuel pump could also be bad, but I'm just shooting in the dark here and replacing parts at random starts getting pretty expensive.
Any ideas?
Oh yea. Vehicle is a 95 5.2L with 170k on the clock. Replaced AIC, TPS, O2 and a few other things within the last 12 months....
