Question about Jeep Cherokee

1 Answer

Code popped on about 2 weeks ago. Since then, i have been getting horrible mileage, it idles rough, and it almost stalls right before i come to a stop, then revs back up and idles rough. It runs fine as long as Im stepping on the accelerator. I have changed the fuel and air filter and cleaned out the air intake tubing. anything else i should be checking? I have a limited knowledge of vehicle repair. I do have an appt to take it to my mechanic but times are lean and would rather fix it myself if possible. 1996 Jeep cherokee 4.0L 140,000 miles 4X4

Other than what you've already checked, a good place to look would be the EGR valve. It could easily account for the bad gas mileage and rough idling. Below is a diagram (top view) of where the EGR is located on a 4.0 Cherokee. Best of luck and please post back with any questions. Thank you.

1996 dodge caravan 2.4 code p1294


on dodge motors
fitted a lot of parts and still no better

the fault code clears and comes back as a intermittent problem

could be electrical voltage drop off or heat related failure

i wonder if your 02 sensor ,the catalytic converter
or other related sensors
are causing the fault to come back
if needed .....fit a new air filter...

how the test is determined

P1294-TARGET IDLE NOT REACHED 3.3L/3.8L
When Monitored and Set Condition:
P1294-TARGET IDLE NOT REACHED 3.3L/3.8L

There must not be a MAP sensor trouble code or a Throttle Position Sensor trouble code.

idle for 40 seconds. One trip fault.

POSSIBLE CAUSES
INTERMITTENT CONDITION

P0300: SOMETIMES rough idle, shake a lot OR less power above 50mph then got this code


Spark plugs in your car are good for 100,000 miles. try changing fuel filter and add a can of B&G 44K fuel additive. This stuff is the best on the market and only available at dealerships. It conditions fuel pump and injectors, also absorbs water in fuel (methanol). Try this first, your car is too new for any other problems. this should help drivability and fuel mileage. If Nissan does not have B&G, I know Toyota does. Also stay with 91 octane fuel. Check oil and coolant often. do not risk overheating in traffic, watch your gauges......

Rough idle, stalling


You must get the system scanned for fault codes, sounds like the electronic throttle control has a failure.

Car stalls and idles rough


On thing to check is the air duct hose that connects from the throttle body to the air cleaner housing. If it gets cracked it will cause stalling problems and very rough idle.
