Take a flashlight and peer down into the hole and look for golden washed spots and pools of fuel.

Did you do this yet? ^^^^

Sorry just got off work...yeah I tried to get the vortec top off this morning and broke to screwdrivers and the T-30 piece trying to do it lol...but yeah ima goto homedepot tommorow and get a new torx screwdriver and open it up..

Ok so I finally looked inside, there were pools of fuel and the whole inside was coated with black grud...im not exactly sure what you mean't by golden washed spots, but yeah thats what i saw inside.

[BlazerLT]

What side had the pools of fuel, the driver's or passenger side?

The pools of fuel are not supposed to be there.

The black crud is normal, the golden washed spots are from the gas eventually washing the brack crud away.

You need a new CPI injector and nut kit bro.

Where do you suggest I purchase the parts and do you know any places online that would have a more detailed guide on this replacement procedure compared to the haynes manual.

Where did you order your parts?

[BlazerLT]

Injector I got off of ebay.

Nut kit and plnum gasket I got from the local chev dealer.

[sykopenguin]

I ended up ordering these parts from gmpartsdirect.com
17113673 - MULTIPORT FUEL INJECTOR - $247.57
17112705 - NUT KIT - $40.20
10105939 - GASKET - $8.12

Question:
Lets say I install these new parts and it doesn't fix my problem what would be the next thing to check out?
I have about $400 left to spend on parts.

[BlazerLT]

Good, this should be the problem.

Let's focus on it for now.

Update:

Finally changed out my CPI / Nut Kit....truck runs great now...no more acceleration problems. Thanks guys for the help. Greatly appreciated!

[blazee]

That's great. Thanks for coming back and posting the solution. There are too many threads in this forum with all problems and no solutions.
