01 Mits Montero Sport P0302 code
 

I am having a continuous problem with this code. My car hits 60mph and then shudders and the engine light comes on. So far, here is a list of what I have had done

Fuel injectors flushed twice
Throttle plate cleaned
Ignition coils switched and then switched back
Spark plugs and wires replaced
Transmission flush

Yesterday, after a week of having another service performed on my car, once I hit 60mph the engine light came on and the car shuddered. It still shudders once it goes over 50 and especially on hills.
Can someone please help me with this.....I have put out about 1,000 dollars trying to find the problem.

Thanks,

Replace the fuel injector or try swapping it.

P0302 Code - Cylinder #2 Misfire
Technical Description

What does that mean?

A P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2.
Symptoms
Symptoms may include:

* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes

A code P0302 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

Possible Solutions

If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are 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.
