Default No Idea whats wrong!!!???

I was at silverlake on sunday and in the middle of my trip my truck was boging out at low rpm's. I cant figure out what is wrong. I thought i had water in my tank but i put water dry in and added more gas but nothing. If i get on the gas it will bog then all of a sudden it will "grab" then its fine if i keep it to the floor. Its not the tranny cuz the rpms go up it feels likes its running on 3 cylinders. I know im getting plenty of gas because my check light flashes which means i have more gas going in than it can burn. It will usually stop after a few miles and be fine. Whats wrong?

Your check engine light flashes and that means you are getting more fuel than it can burn? Don't think I've ever heard that one before.

FWIW, one of my friends had the same problem and it ended up being a plugged cat.

try cleaning the mass air flow sensor, use carb clean or throttle body/mass air cleaner from 3m, sometimes it affects low rpm running, either that, fuel fitler, fuel pressure, cap/rotor, or plugged cat, what year was the truck?

Check your fuel filter. If it's getting plugged, it'll cause bad bogging too. A flashing CEL is usually an indication of a mis-fire.

the only reason the mil blinks is when the engine is missfiring bad enough to cause catalytic convetor damage, probably in the dist. cap and rotor. make sure to check the play in the dist. seen the dist drive gear worn badly on these engines

Not trying to piss you off I am trying to help you. Check engine lights dont blink because of to much fuel they blink because of a misfire. What year is your truck? 1996 and newer will tell you what cyl is misfiring. That will point you to a bad plug wire or plug on that cylinder...however if the scan did not point to one bad cyl I would suspect a bad coil, ignition module or pick up coil. Any of these would cause a misfire on random cylinders and make the check engine light blink. This is not going to be a fuel system or cat converter problem...it is definitely an ignition problem.

EDIT: What did the scanner tell you?

x2 if you dont have any cats on it to plug up and its not fuel related this is the next place to look

X2, very rare,but could also be an injector failure, have seen the injectors fail on the spider injector

dont use carb cleaner as it will damage the sensors. you need something that is designed for cleaning the sensor like mass air cleaner. Not trying to point a finger at davidkassie, just making sure you dont hurt something
