welp, no luck on the idle / rough running (yet)..
new plugs plugs, plugwires, cap 'n rotor, different AFM, different aux air
valve, oh and different injector resister pack (just for the hell of it).
with the o2 sensor plugged in, the idle is at 1800rpm (as stated below). we
disconnected the TPS while at idle and it dropped down to 1000rpm indicating
that the tps could be whacked?
not sure where to go next but i'll keep you guys posted.
