Sluggish crank

**Fubisin** · 09-10-2009

I have a problem!

I have noticed that sometimes, not always when I go to start my 04 GT, it fires but doesnt seem to fully fire and sometimes fires but then "boggs" out and doesnt start. Its hard to describe but it will turn over but instead of a total rev it is a rev then a drop then either the bog to not started or a rev to a drop then a sluggish idle.
ANY IDEAS!
I just called the garage but I havent talked to my guy yet.
I was thinking running the tank somewhat dry, replacing the fuel filter, fuel lines and 3 step de-carbing my system.
Its pissing me off because when I go to show someone, it fires no problem

HELP PLEASE

PROBLEM SOLVED a while back, just a update.

I took it into the one of the GM dealers up here and they called it a "hot start"
Didnt give me much details except that it was a simple computer update and a throttle body clean. Did it, now it runs great, except I have noticed it doesnt have the same balls it used to??..??

Cleaning the throttle body every 10K or so does wonders for those drive by wire cars...I say if you change your oil every 3K clean the throttle body once every 3 or 4 oil changes...I just did it on my '07 Cobalt with 35K and it was NASTY
