Thanks guys for all the helpful post, I just don't feel comfortable doing It myself, I do my own oil changes, fuel filters, air filters, and that's about It, but I did call most af all the local chevy dealers around my area and they were all about $100 from each other, merchant automotive ( the DURAMAX GURUS) out In Zeeland, Michigan was about $300 cheaper than the dealers but It's about a 2 hour drive from my house, so with the added fuel expense, and the $100.00 for the diagnosic charge I just told the STEALER to do IT!! I even called a guy who has his own garage (kind of a buddy of mine) and he said he'd only be able to save me maybe $200 If I was lucky over the dealers price, but I want to say THANKS on posting the INJECTORS DIRECT .COM website, I will buy atleast 2 extra injectors from them just to keep In the garage in case this happens again, which sems kind of common on the d-max, they are cheaper, and I can have the guy I know with his own shop Install It for me, and just pay him labor!! Again a big shout out to all you D- Max boys for all your help, I LOVE this SITE!! Mike!!
