ka miss firing at full throttle

[brandon pico]

Car was runing decent before, then added msd 6a box and a blaster 2 coil and was sounding real nice, then hit it with the timing light and the timing was way too far advanced like 30 or more, so brought the timing back to 20- ish and then the miss firing started at wide open throttle, but will go smooth if you baby the pedal till open. So I unpluged the msd and coil back to stock, reset the timing, and still runs like crap....

Any ideas?

check for codes
fuelpump voltage...
fuel pressure....
also 12v from the ignition circuit since u had the msd on there...
i had a 6a on my ka and it ran bad try just the blaster 2 with drop resistor

Maybe put the timing back to where you had it when it was running good?

If its not broken dont fix it.

your not getting enough fuel or you suck at doing timing cuz you probably didnt let it warm up unplug the tps n have it at idle of 800-900 rpms


but thats just what i think
