Some peoples' kids (Duramax owners).

I get to take this one back apart since the guy brought his own injectors from NAPA....

#2 overfueling.

GRAND. I won't have that injector until Tuesday....and it just has to be on the hard side (even bank).

If once isn't bad enough, twice certainly sucks.

Were your fuel trims out, puffing black smoke at idle?

[cleatus12r]

Slight knock at idle and 13% balance rate on that hole (when the rest were + or - 1).

Not acceptable. Runs like a mad chief though which is better than I can say than it did before. Anything over 1/4 APP and the thing would start frickin' rattling to beat the band and smoke out both lanes.

LOL


About 8 hours later I got mine finished up, runs a little better with injectors that dont look like this......

After the first half dozen, you'll get it down to 5 hours.

I got this one buttoned up this afternoon. It's amazing how these trucks even run when the inlets get clogged up (by the way, you ain't got nothin' on the last two sets I've done).

I have only done a couple D-Max injector changes so far (thank goodness), but I was still able to beat book time.

Now if only there was a better tool for popping the injectors out I could save a ton of time. That stupid OTC tool and a screwdriver cannot be the most efficient way of doing it.

I am surprised it ran as well as it did, only complaint on my RO was a haze at idle, otherwise ran fine.

If you want, I can send you an old injector line I modified that you can grab onto while twisting and pulling....also I weld a lip onto the big end so one can use a 10 inch prybar and use a rocker shaft bolt to pry against. I've got at least a dozen extra lines, so it's no problem to send one.

Yep, underfuel at idle (white haze) and then the severe overcorrection at all other times.....

It's amazing how one of these trucks can overfuel when all of the inlets are plugged solid. The one I did previous to this one had so much crap in there that it was nearly level with the top...but you couldn't keep it from fogging out the whole highway when rolling into it.

Oh well. Money in my pocket and a happy local since he can drive his truck again. The next one I do I will be sure to let the customer know that if he wants to go "cheap" on the injectors by buying them somewhere besides GM, I will charge extra if I have to tear it apart again. NAPA won't reimburse my additional time to go back into the even bank to replace one of their faulty injectors that lasted about 5 minutes. I won't even worry about actual Bosch remans from GM. Dozens and dozens of those and I have NEVER had a problem.
