*update
Today i got new acdelco iridium plugs , and ... some brand of ignition wires (not oem, but good).
Pictures are worth 1000 words. After 3 busted knuckels and a slashed finger, i managed to replace the back ones too.
Symptoms: misfire(+code+CEL on), hard engine start with cranking for copple seconds, huge loss of power.
Coilpacks need replacing too from what i found. Ima order them ZZP ones, $100 a set, ppl say they is good.

Wires, they were shot.
Spark plugs? well... here it goes...
As for my ABS code and lights, my buddy found the problem: ground wire from ABS unit.
Drove the car today after i finished, i also fixed the little vacuum leak by the battery.
Guys, i kid you not, its totally another car since the drive yesterday, i think i woke up the monster. Its alive!
I am happy where i got so far. Vert happy. Runs like butter, crisp throttle response, pulls like a locomotive, the nose comes up hard, and i think i saw 7.2 PSI max on the dash boost . Is that normal?
The only light that doesnt go off now is the LOW COOLANT, wich it has plenty both radiator and expansion tank... will look into it next days.
. Got a glovebox intact for my regal for $6.50 ( yes six dollars and fitty), and a jetta floor mat for $1.50
