Are you getting a strong signal to the ecu.Is it reading rpm ok.

hi,
i`m using some mercedes injectors, not sure what they flow.......am
running boost retard canister.i
have fitted a malpassi reg, and it still ran the same, i then closed
plug gap up it was 98 percent better.i
hit boost about 5 times. no worries...
THEN it was idiling funny,put my foot on the pedal, and it
dies down, cant get no revs, i pulled the vac line going
to the digi one, then after a quick stabon the pedal, i could get
it to rev pretty well, and actually drive it, maybe
the reg settled down , and needs the fuel pressure reseset?,
i`m getting a pressure gauge tomorrow, and check it out then.

Mark,
Are you still using the factory injectors???? I remember u asking about
injectors.... If so id say that is your problem. My injectors wouldnt flow
much more than that. With the malpassi reg, ca18 inject, and good fuel
pumps i was able to run 22psi+ easy. As for the ignition i ran a
S2 dizzy - which i think your running??? Have you fitted a boost retard
unit and sorted it all in that regard?? If so then run some BPR7ES plugs
(or 6ES's) gap them down to around 0.6mm and youll be right!!!!!!!!!!!!!!!
Then boost up 10psi is ordinary you want to at least double that....
Steve.

I would be checking
the fuel pressure while this is happening. If your regulator is not
responding to the boost quickly enough then it could be lean. But
that would be after I checked the plug gaps.

Sounds like it's running out of something
- if it feels like fuel then it's
probably spark

hi, as it approaches max
boost (10 psi max) , you will be accelerating,
then it would cut out
for a tick, then accelerate again, then it would ,
maybe sorta run a LITTLE
funny for a bit , then accelerate again, .
most of the time this happens in the
period of about 2-3 seconds, then some
times it might happen fractionally.,
then once in a while it will be okay.
i will check into those plugs.
