I'm sure i can read a scan or two, why don't you post some up? There's plenty of darn good help on here to give you a pointer or two and maybe help work out your problems? FWIW I trap 106 non-i/c'd on 1.9 rockers, so... I would first change your plugs to 104's those 103 are way cold for that setup, another i have a feeling of a vac. leak, maybe check around for that?
We are tuning with a power tuner, so we can prolly post scans.
Vacumm leak?I just might have one.
104's over 103's why do i need a hoter plug?
I thought colder was better?
