im investigating my lo3's tendency to bog. by 'bog' i mean that with any amount of throttle when cold, rpm's drop. also, when warm there is a hesitation when 'romped on'. timing is fine, all sensors hooked up, no more vaccum leaks (had to replace intake gaskets a while back), no ses light.

i meant to look at the plugs but didnt. plugs the culprit?

 

My friend, the plugs are the best diagnostic tool in the world.

 

Whats the fuel pressure? Hook a gauge up and stab the gas. If the pressure noses over, then you need a new pump.

 

will check... lol, dont know why i haven yet.
