OK, i just reached 150,000km on my truck and decided to change the infamous spark plugs. After getting the tool and read the forum ( thank you for the excellent information of all the people who posts the information ). Only 1 out of 8 plugs broke and the tool was easy to use.

When i put everything back together, now my truck is idling so ROUGH, I realized i forget to plug the connector back in for Injector #2...but even after all electrical connections are checked, and the truck still idling very rough. When i drove to work this morning, the Engine temp surges to 3/4 way up ( 240F according to my programmer which i know it never gets that high ).

Some info that might help :
- I used MC SP515 ( that's what the dealer gave me ).
- I get a "Onboard diagnostic test not complete error" on the computer.

Any help or suggestion is appreciated!!!!!

Thx

 

Any dtc codes?

Are the cops installed correctly?

You didn't accidentally forget a connection or bump something loose?

 

Thx for the reply :

That's what i was worried that i mixed up some of the wiring or knocked something loose.

DTC codes : I got an Open circuit on cylinder 2 and fuel system is too lean .

I realized i forgot to plug the injector connector when i put everything back together. Even after i plug it back, the codes clear but still idling rough and engine seems to run hotter.
