hi, My 97 ex choke and sputters when press the gas when the engine is cold, if I wait until it reach operating temperature I can drive it but with a choke at take off then rev's fine always you not make a WOT pull.

No CEL!!!
LS VTEC

 

I forgot that the car always start the first time, now it dies the first time start it again and stay in normal idle.

 

ECU?
Mods?
Any maintenance done?
Does your CEL work?

 

ECU P06 chipped and vtec converted. (tested in other car fine)

Fully build block
JE 9.0:1 pistons 81mm (tested last week 200 across the board)
Eagle H rods
Sleeved
B16 head port and polish, Supertech valve train. ITR cam IN/ GSR EX.
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.
New fuel filter
New Dizzy
New fuel regulator (AEM). This was my first suspect the old B&M.
Switch TPS .46 - 4.58

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.

 

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?
