I have an 05 with 107k I think I have at least one injector going bad
I got a code once for number 8 cylinder contribution and now I have to plug my truck in when it's almost 40° for half an hour and it's still spits and spudders for way too long and smell diesel from the exhaust, but once she gets warmed up she runs great. Just wondering what you would do in my position. -Thanks for advice

 

 

The only other codes iget is ICP low which I've never seen ( tried unhooking didn't change) and crank sensor which I changed last year cause I got that code ( popping up again) and the fuel gauge will quit working sometimes. Both ways either will show full when not or won't work at all that I get codes for. I just have the cts insight for checking codes. I'm kinda wondering if it could be something else. I tried starting it not plugged in but let the plugs work for 5 mins by cycling the key every minute and at first it tried to start then it would just crank and not try to start. I guess I need a scanner and a trip to Amazon. Wierd thing is once warm will fire right up like normal

 

Can I just change the top part the oil goes in or is that not a good idea
