Precision 650cc saturated injectors (12.8 ohms in 3 of them and one 12.6)
Walbro 255 Rewired (lately the sound change to louder) maybe I'm paranoid.

Yes the CEL stay one 2 seconds and turn off, if I unplug any sensor the CEL pop on and i can read the code. I'm making this tests with the engine pressurized and not and the same.

Is your car tuned or is it just a base map? I'd check ignition and cam timing as well.

carlos8

Yes the car is dyno tuned and work perfectly for 2 years without problems.

Not my daily and good maintenance.

When I put the new dizzy I set it with timing light.

The cams and crank are in spot. But really weird the car sometimes rev's like it is retarded ( very sluggish/laggy).

HondapartsHero, You think this can be a going bad pump or a clogged intermittent faulty injector?
