iv'e just got the car running great after sorting out problems with fault codes and since then i have bought and fitted a pipercross induction kit.
i took the car for a quick drive and was dissapointed as it has actually slowed my gte down, the car now has more dead spots than a cemetry just after the black death!.
iv,e played with the co'2 pot and that makes a difference, but as soon as i think iv'e got it running well and i come to it the next day to drive it to work again, it runs like crap again, the cars got a mind of it's own. what's going on??
p.s the engines not idleing too well-there's never a constant throb from the the exhaust, it sound like it misfires sometimes, iv'e cleaned the system with carb cleaner, cleaned the dis cap ect, and have farily new sparks and leads etc.
the co2 pot only adjusts the mixtre at idle. The ecotec valve thins your mixture, ive read teh ecotec site and it says every where we gained 30mpg blah de blah, its cause its thinning your mixture out, not because its swirling the mix and making it burn better.
I reckon, mod the original air box (drill the bottom), fit a +n panel filter, ditch the ecocrap valve, reset the ecu, happy motoring
