Fuel/Throttle cuts in and out on highway
« on: December 20, 2016, 02:35:19 AM »
98 XJ Cherokee, 4.0 manual. 4.10 gears, 33" tires. 340k km. Recent plugs, wires, cap, rotor, Bosch fuel pump.

Fuel cuts out, and in and out, and out etc on the highway at whatever throttle position I'm holding speed at. If I mat the gas, she goes. Happens around town once in awhile but without fail trying to maintain 100-110km/hr.

A previous search suggested crankshaft sensor, but I'm on mobile and that's no longer coming up.

Any help, suggestions, post referals would be appreciated, thank all!

Further search suggested throttle position sensor, tested ok.

If you havnt done it recently then I'd start with the CPS.

When you cycle the key do you get any codes?

I would also check your throttle position sensor...
