When driving my car starts jerking out of nowhere. It feels like the car looses 80% of its power but still struggles to move if I keep on the gas. If I let off the gas the car stalls out. I can flip the key on and off and it turns right back on and usually it goes away. I am getting no CEL and i hear no strange noises or anything while this is happening. I am clueless as to where to start looking for the problem. Im thinking its not mechanical because it runs perfect at times. Any ideas?

I have an LS/VTEC with a chipped p28 .

 

What's your fuel pressure set at? Any V-AFC, FPR or anything?

Check the color of your spark plugs, sounds like you are running lean.

 

sounds like fuel pump is starting to give out

 

check your fuel pump and change your fuel filter

 

sounds like a fuel problem, also check injectors

 

does this only happen when its cold and or wet?
