hey i just bought 1998 2.3cl and i go to dealer to change oil and my check engine was on. i asked them to check it and it come misfire.. they still don't know where the problem came from & the worst thing gonna happen is I need to rebuild my engine.
is anybody ever have the same problem w me??
Is that true that the worst thing is i need to rebuild it??

 

If the dealer can't diagnose this then you should take the car somewhere else.. it sounds like they're incompetent.

- coils
- plugs
- wires
- ECU

 

no comment.

 

Most likely your timing is off, either that or you have a bad sensor, if neither of those, then maybe a crack in your distributor

 

It sounds like a broken valve spring, do a compression test, and observe the action of the needle on that cylinder compared to the others...if the needle acts strange, it could be a valve not seating correctly, or lets say simple spark plug problem?

 

how to do the compression test?? i never heard about it

 

the cl i just bought was throwing the same code...i cleaned the egr ports in the intake manifold and the car now idles perfect and the code went away.

Just take off the fuel rail and there is an access plate, take that plate off and you'll see the four holes for the egr clean them with an awl, bottle bush and carb cleaner. Also be sure to clean the underside of the cover. Mine was throwing a cyl 4 misfire and i swear there was so much carbon it was actually packed inside ithe intake manifold, most likely at best it was severely obstructing the normal air flow into that cylinder. All 4 egr ports were clogged solid.

That said a misfire could relate to alot of things obviously...plugs, wires, cap and rotor or the dizzy itself. Also check the ignition timing.
