I have 2000 h22a4 in accord w/ strage 2 crower cams, supertech valves, valve springs and titanium retainers.

Most of the time when the car hits about 5000 rpm the car sputters and the air fuel gauge reads lean. I was wondering what could cause this. I am running 48lbs fuel pressure and have aem fuel rail and 310cc injectors. Some people have said the wiring but that isnt the case b/c it has ran fine the past year. This didnt start happening until after i put the cams and valves and stuff in. Also when i put all of this in i added the msd ignition. Someone told me that the msd could be the problem b/c it could be sending to much voltage for teh distributor to handle. Can someone help me with this problem????

 

what kind of injectors are those? saturated? peak-hold?
are you using a fuel controller? is so which one? if not you may be running too rich.
what are your plugs gapped at?

 

i have the 310cc RC ENGINEERING injectors....i dont have a fuel controller.....the spark plugs are brand new denso iridiums....they told me they were pregapped and not to touch them or i could break the electrode.

 

try lowering the gap on the spark plugs to .035 or lower. you won't break the electrode. and if you don't have a wide-band o2 sensor, you don't really know what your air/fuel ratio is.
