Here's a little tip: If you have a rough idle, or it idles high, take some carb cleaner or brake clean, or eather, and spray it around the bottom of the throttle body, where the throttle body meet's the intake. If there's a change in idle, that's where the leak is, and that's where air is getting into.

With those two DTC's "P0171 P0174", you either have a vacuum leak / intake gasket leak, clogged fuel injectors or a bad O2 sensor.

2 bottles of Lucas injector cleaner are not going to clean fuel injectors that are dirty enough to set those codes.

tnx gunman and zx and everyone else with ideas, and suggestions.
truck is in the shop under my extended warantee and the shaft seals are leaking to.
they were supposed to replace the manifold gasket, hope that fixes the problem.
02 sensors we replaced a week ago, manifold is neing done at the chevy place, new iridium delco plugs, new wires.
if this doesnt fix it , it is most likely the inkectors clogged up, or the vacum leak like you said ZX.
thanks alot guys.
Shayan G.

hey guys,
i got the truck back from the dealer. it is less than 4 miles from my house. half way home truck died, cranked right back up, so i didint think much of it. then i got home, went inside, and 10 mins later came out to take my mom to work, truck wont go in gear. stays in park. they just did front end work, (SHAFT SEALS). and i think they broke the linkage or soemthing in that nature. i just got done paying 689.11 to mikemorgan in shreveport, la. mmmmmmmmm.......
