hey i own a 2005 LT tahoe with a 5.3L V8 and ive recently been experiencing a lack of power from a stop.. i only experience this if im at a stop sign crossing a busy road and i floor it too quickly get too the other side. but when i floor it the truck seems too bog down and crawl its way across, until about 25 MPH when she starts too take off like normal. basically the engine seems too bog and others have said "trip over itself" until about 25MPH, and it only happens at low rpm. ive learned that i get more power out of the truck at half throttle, than when the pedal is too the floor.. which is weird because ill have the pedal too the floor and when i try too let off because there is a car in front of me i actually proceed too accelerate more at half throttle. my knock sensor has been ticking for a while now does anyone thing this could be a reason to why this happens? maybe it could connect with the fact that when i put gas in the truck, she likes too spit gas out of the funnel if i put it in too fast so maybe somethings clogged? im pretty sure this truck is also on its stock ignition plugs and coils, so maybe a tune up would fix this?? should i order new coils and plugs or can i get away with only buying plugs? because ive checked for miss fires and i have none from the coils, they all function. maybe doing a plug change would improve performance?
