Hello guys I've been trying to correct my problem that my truck is having but cant figure it out. When I jump on it wot it pops and chugs thru the intake if I keep it pinned it will still do it until I let off of it then if I pin it again it will start doing it again any ideas like intake leak or anything along that line? any help will be appreciated. Thank you in advance.

 

Do you have a Wideband hooked up....if its a backfire pop, you are lean. If its a bog and killing the engine(so to speak), you are rich.

 

i had a popping problem and couldnt figure it out, billy at TRT insisted on it being the cam, being a custom grind, well it was the cam..and problem now solved dunno if this is your problem but it was mine

 

Check the valve train. Loose rocker, Bent push rod, broken valve spring.

 

it could be an exhaust lobe on the cam that's rounded out causing the exhaust valve not to open making it pop from the intake. could be many other things though.

 

Or the cats are starting to clog.

 

would it be the cam if it changes when it gets warmer out? it does run better when its warmer out. I might have my buddy video tape it so you guys can get a better idea of what is goin on.

 

Nelson is sending me a new tune he thinks the pcm i got is bad. If this doesnt fix it im blowing it up because everything else seems good.

 

So lets say my cats are cloged should i remove them or have new installed. What would be the best idea. Thank you
