fail emissions
 

what do u guys think. said ran 50km before test,

You may need to drive a few mores and get the other monitors to run, or have the dealer see if they are any updates for all of the controllers.

p0302 is the error.

From my dealing with this code, replace the cylinder head. Even if it a 4.0 engine, I have seen the same problem as the 3.6 engines.

even on a 1998? wow really on a 4.0l? would there be signs? I seem to notice that the intake on mine when I pulled the throttle body to clean so signs of heavy film of oil in it. oppsosite to the throttle body by the battery side I notice that the plastic seam off the intake shows bit oil like if its cracked maybe?

mastertech whats the firing of the cylinders of the 1998? this is a mitubishi engine right? http://www.justanswer.com/uploads/am...59_3_liter.gif


if they wired the first 3 in front could it possible give out this code?

If it's a 3.0 then yes its a Mitsu 6g72.

Code 302 is a cylinder 2 misfire. I would check your wires and make sure everything is where it should be. Also check for vacuum leaks as they can cause a ton of issues.
