Alright here is the deal, Bare with me.I bought my truck in may of '05, truck was fast and powerful, hence the purchase. I loive in colorado and this truck would run up and down the hills no problem. Had no problems for a year until the fuel pump and vp were replaced under warranty. Since getting the truck back in May. It goes 20mph slower up the hills, It has a shudder when starting in 2nd. At idle in gear it used to let the engine take the truck but now it almost idles to stalling. Basically all the mods I have made have been in a vane attempt to get the beast back to its former glory. Even with the Juice/at it does not quite sound or feel the same.Brother came out and even acknowledgedlack of *****. Truck used to grunt like a pig. I need any suggestions people have. I'll take any thing. I just need ammo to fire back at local Svce manager.
Sorry about long thread. also installed blue so good fuel pressure.

 

Anyone! Anything. DEaler said no problems to be found.

 

That's a hard one. Maybe the new injector pump was not up to par. I have no idea how you would convience a service writer of that......since it's hard to get them to believe obvious problems some times.

 

i got 1 idea on the no ***** part did they/or you tap the wire on the new vp so that your getting the extra out of the comp

 

Positap put in after orig. problem. 2nd post

 

Did notice a litt le slack in drive belt but do not think that this is an issue, problem coincided with dealer fix.

 

1 other thing just off the top of my head have you unhooked the edge and see if that helps the idle /and shudder problem/ buddy had a edge ez (i no to completly diff boxs) that went bad and made a shop think his vp was bad after speding 1800 bucks he bout a new edge and was back in buissness

 

Have un hhooked edge .associated w other problem, 1st box killed map sensor This is not related to problem, I'm beginning to think that mechanic saw some thing he liked and took it. It appears to be a mechanical problem, engine is good but does not correspond to drive train response.

 

Spoke to dealer said they may not have updated ecm at time of repairs. So they will take it and do all necessary upgrades. I'll keep my fingers crossed.
