If this is hesitation and unsteady idle, check for vaccum leaks at the intake with starting fluid. Frankster016

Wont start after replacing spark plugs in 2006 jeep wrangler


Hi my name if Tom and I am here to help.

The most likely problem after changing plugs is that you got the wires to the wrong plugs. I am guessing.
Did you change one plug at a time or pull all the plugs and changed them as a group?

If you did not mix up the plug wires, I would need more info to help you further. I trust this info was of help. Do not hesitate to get in touch with me at your convenience.

My 94 jeep wrangler has a 99 engine in it as I take off in all gears it hesitates and back fires. We checked the injecters and changed the plugs and wires and distributer on it. It is still doing the same...


99 Engine is OBD-II.

It must match with the same production line ECU.


You may luck out by getting the chip set for the ECU.


Did you purchase the 99 engine,ECU and the wiring set OFF THE SAME Jeep.

The key is to have a matching ECU firmware to drive the injectors and read ALL sensor.

Go to pick and pull and check out few ECU stock numbers and compare to your

==
There is a "S" for stating it's an auto or stick.

The CPS crank position is differnrt between the two.

This can be your major miss-match.

99 jeep wrangler 4.0 backfires and hesitates


Fairly common problem. Typical scenario is start vehicle, runs fine for 15 to 30 seconds and begins to backfire when placed under load as customer tries to drive vehicle. Flooring usually makes the problem go away. Usually does not throw a code.

Fix is to replace the upstream 02 sensor.

Jeep Wrangler Gas Consumption and Loss Of Power


If its using a lot more fuel than usual its almost garaunteed an 02 Sensor. Those are located on the Exhaust Manifold's, are about the size of your thumb, and generally have 2, or 3 wires coming from them. If you can, check them for operation before you replace them as sometimes they're kindof expensive.
