Engine codes

No power while accelerating, no wrench or MIL light, pulled codes, 0300, 0303 & 0307. Any ideal of what I need to look at or where I should start? Thanks. Coach.

It's defenitley misfiring on 3 and 7 plus random misfires. Have you looked at the ficm values?
Is it more of a cold issue or all the time?

Start with batteries/ ficm values. Have you replaced the fuel regulator spring?

Possible you have some injector problems........rule out the simple things first.

I do have the blue spring upgrade, batteries are new, this happened after 30 minutes of driving I noticed the reduction in power, I neglected to look at the ficm volts, and it's all the time now. Where is the best place to get rebuilt injectors?

May not be injectors. Check the FICM first. Could also be injector stiction causing issue. Might be worth getting some Rev-X and trying that before replacing injectors

Only thing you could do is take it and have a power balance and contribution test done to make sure.

I made an appointment next Thursday with the dealer I bought it from, it's about 45 mins away, the local dealer couldn't get it in until after Thanksgiving. If it is injectors, where is a good place to get rebuilt injectors?
