Jeep problem 2

[frosty9595]

I can unhook just about any one sensor on my car and still drive perfectally...... maby a bit of power / gas milage loss but still drivable. My maf sensor died on a road trip last year and the car bairly ran.... unhooked the maf sensor and drove home.... just got like 18mpg insted of 27mpg

my friends jeep has the same problem except his got really really bad and only goes 10 km/h foot the the what did you change to fix it sensor?

[metuber11]

its not the temp sensor its the throtle body sensor

[gibsonlespaul2]

It's the Temp Sensor, The car actually dies and restarts when he revs it.

[teamlawless17]

oh sorry didnt see you already fixed it

[teamlawless17]

sounds like the temp sensor

[PGMEagle]

Sounds like the engine is blown almost

[johnnybsic]

temp sensors. all 4.0s do it. I keep one on my tool box along with a crank POS.

everyone replaces the tps, but it rarely fixes it. especially backfires (has nothing to do with a TPS.

Isn't the XJ a truck?

[jimcantplay]

its a jeep

[quailman8760]

the mj is a truck aka the comanche, the xj is the cherokee

[DavesAV6]

Fixed... It was the temp sensor.

[Cazador42265]

cool-

[bowmaster24]

Haha good job man. Glad you got it in condition again

[discoveryman]

@DavesAV6

the temp sensor that did that???...wow the ECM on you rig must be strict.....i miss the old days when most everything could be bypassed if needed LOL.

[deafdude6]

@DavesAV6 try check vacuum hoses too. its would be cause those sensor problems like mine with my 1987 jeep comanche then now inline 6 run smooth after fix hoses, tps and temp :)

[jeepcherokee40]

@DavesAV6 I know its been awhile but you would you be able to tell me if it was the sensor by the firewall or the thermostat?

[DavesAV6]

@jeepcherokee40 theres 2 of them, I think the second is in the back of the motor.

[benchmaster200]

it sounds like its missing maybe plugs and wires and a induction service

[devon91reed]

at least it will have all that new stuff on it.i know the coil likes to short out on them from high rpms.that causes it to act up.

[Alex0992]

Pedal in reverse, computer problem.

[DavesAV6]

replaced TPS still does it. Now I guess time for the ecu. Thats all thats left I think.

[dint500]

need a tune up

[DavesAV6]

all brand new ignition system and fuel system.

[XJFiles]

yup, backfiring and strange accelerating.

just happened to my friends. was the same (tps)
