I purchased my "new" truck - a few months ago in Lakeland Florida, drove it home to detroit area knowing I was most likely going to be doing an injector rebuild by the way it ran.... rough and smokey.
2001 cc lwb srw 191k, lariat, auto 4x4, all stock for now
After I got into the injectors with the Rosewood DIY kit and found they needed some machining - I sent them all back to Jim Rose for rebuilding (he credited the rebuild kit price - great guy to deal with)
I replaced all 8 sleeves #7 was wheeping coolant)
glow plugs
rebuilt the turbo
gutted the EBPV
and replaced the up pipe donuts while I was at it.
After putting it all back together again - I still have a miss, and a cylinder contribution test shows #8 failure
(before all this work 1,3,8 would fail)
there is a noticeable miss at idle cold and warmed up,
and along with the miss - white smoke out the tail pipe.
On a whim last night I decided to swap out the CPS with my spare
CPS - newer gray and older black CPS - NO CHANGE for me, I've read that others have had good luck swapping to the new dark blue CPS... maybe worth a try, apparently they can be had for $19 online.
I put an ohm meter on the valve cover pins and all injectors on the driver side showed the same resistance - so I don't believe I have an UVCH problem - though I may pull it apart to be absolutely sure.... The UVCH appeard to be replaced before I got the truck - the wires to the GP were still bright white.
The oil pressure sensor in the front of the driver's cyl head also appears new.
I'm open to any and all suggestions - I'm trying to come up with some ideas before pulling it apart and swapping injectors to see if the problem follows the injector or stays with #8.
I dread the thought of pulling the harness apart searching for chafed wires between the valve cover and the IDM on the driver inner fender - but that maybe in my future as well....
What say you?
