I have an 03 X with 225k on it. I put 8 new injectors in it because I was leaking fuel into the engine oil. I got them from dieselogic from ebay in Jacksonville FL. 4 of those were leaking and they warrantied them. Then 2 of them were getting contribution codes and they would not warranty them because they said I had fuel contamination. They did not send them back to me either. I got 2 more from advance auto parts. They were working fine. For a little while. So now here is where the problem is. I was getting a cylinder 1 contribution code. So I swapped cylinder 1 and cylinder 3 injectors. That code is gone now. Now I have cylinder 4 contribution code. I swapped 4 and 6. Still have cylinder 4 code. When the engine is cold it runs perfect. When I drive it for about a mile or so and come to a stop sign it's still running perfectly. While I'm at the stop sign it's like someone flipping a switch and then the misfiring starts. And no codes until the "switch" is flipped. Ficm measures 48 to 48.5 at all times. I don't see any chafing of wires. And I forgot to mention that I had a leaking fuel into the oil again. Ran another dye test but did not see any signs of leaks this time. But that was after I swapped injectors around. Could have been leaking from the orings. I can't can't figure out this misfire. So I was thinking compression test next but why does it run fine when cold?

 

My wife wants me to get rid of the truck. I keep telling her no. Every vehicle has its own set of problems.
