Recently I've been getting the PO300 code, typically right at the end of a 3rd gear pull. I'm just curious if anyone has been able to resolve the problem by using an ignition amplifier such as the HKS DLI-2 or by replacing the stock coil packs with a coil-on-plug setup. Anyone that has used these setups, do you think they would help? Thanks,

What is your plug gap? I used to get alot of these codes. Then I dropped gap down to .024". Did get any more codes.
I have since installed a custom COP set-up using 300C coils and MSD DIS-2.
Now I get a miss w/ rpms higher than 3K and slight cruising throttle. I'm pretty sure it running lean in this lower load site. I just need to richen up (I'm running a custom Dynoflash).
I am now able to increase plug gap tp .035" and have strong acceleration and great high rpm (8000rpms).
I have H2O/Meth injection pushing 15% water/fuel ratio and boosting to 25psi.
Idle is slightly better ( I have HKS 272 cams/gears).

 

When you say you get a miss w/rpms higher than 3K and slight cruising throttle do you mean P0300s?
