Through two codes last night P0300 Ramdom/ Multiple Cylinder misfire detected and P0171 System too lean. This is some new stuff to me. Luckly I do have 440 cc injectors all ready and some hotter burning spark plugs.

What's the odbII scanner that works with Palm Pilots?

Finally got a chance to get on the dyno a dyno and see what was going on. Lean as HELL with no fire. Put the 440cc injectors and -1plugs in and still lean.
Man you want to talk about pissed right now. But will am going to haul it to CP next week and hopefully get everything taken care of.

What other mods do you have that might be leaning it out? Leak?

I have pluem spacer turbonetics said that that would not cause the boost to stay so lean i also have headers.As far as leaks go i do not think i have any but they say that ther is problem with the way i installed it. I will see in a week or two.

Do you have an AFR gauge? How long have you been driving it like that?

If you have no leaks:

At idle you should read A/F ~14.7, vacuum ~20-21.

I'd double check how well your plenum spacer seals, a boost gauge isn't going to catch a leak at the plenum.

Are you boosting to 8psi?

Any kind of boost leak at the plenum will make you run lean. On g35pms car his plenum was leaking and he was running lean and pinging. As soon as the leak was fixed his power and AFR were perfect and he didn't ping..

Yes but not yet installed. I have not even been driving the cra due to the rough starting i have been haveing with it.
All the screws in the plenum are tight. NO boost guage yet i am waiting for on to come in.
