Question about Jeep Cherokee

1 Answer

I have a 1998 jeep cherokee 4.0l. I just replaced my spark plugs, wires, cap and rotor. I also replaced all my fuel injectors. when I begin to drive my car it feels like I am losing power as if I'm not getting enough fuel to my car. I call it a hesitation. This only happens if I begin to drive at a slow pace. If I get up and go there is no problem at all. What is wrong with my car.

just because you bought new does not mean it works

You really should be using a good manual as a guide fro testing. For wiring diagrams chiltons is better than haynes. Have you checked power flow through the ASD relay??

What would cause a cylinder 5 misfire in my 2002 jeep grand cherokee 4.7L


A misfire may mean that one or more of the following has happened:

Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

If you notice symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

You haven't changed everything...map sensor controls spark and fuel mixture as does the throttle position sensor, also check the idle control valve...Don't just buy stuff...do testing first.

92 jeep cherokee wont stay running


Check the fuel injectors and rails for clogging or maybe a seized up ECU. my only other thought is that your throttle position sensor may be shot.

My jeep grand cherokee is smoking really bad. Black smoke and it also skips. What might this be?


Black smoke is too much fuel. Bad spark plug, or plugs, bad spark plug wire or wires, bad injector, allow engine to cool, pull the spark plugs. does one look bad? Replace one or all. Plug wires don't last forever. An injector can stick open an pass too much gas :)

1997 jeep cherokee 4l will not start on petrol or lpg


Here are a couple of things that could be causing your problem. 1. Bad ignition coil or ignition module 2. Clogged fuel filter 3. Clogged air filter 4. Clogged fuel injectors 5. Bad spark plugs, wires, distributor cap and /or rotor. 6. Broken timing chain/belt. Here are a few things you can try to verify that you have a good spark. 1. Remove the distributor cap and crank the car. If the rotor turned you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. 2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module or ignition coil is bad. 3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.
