Hey guys, I've been having this problem off and on since November or December of last year, up until January February. Now all of a sudden it's back.
The truck seems a little low on power. I've got to give It more gas than usual and the rpms shoot up higher than normal. Like it's struggling a little. I'm thinking it's either the fuel pump or the throttle body. Throttle body has been cleaned. Does this in hot or cold. Also has stalled twice at a stop sign. No codes. Plugs should have less than 20k on them. Truck has almost 150k. Anyone have any ideas?
Thanks

 

I would suggest doing a compression check on each cylinder and report back the numbers

 

When was the last time you cleaned the TB?
Al.

 

Throttle body has been cleaned earlier thins year, I don't put many mines on it anymore. The tb is still clean. I can look into the compression check.
