Installed 10psi pulley and car is now playing up!

[CHARGEDVT]

well as the title says i installed a 10psi s/c pulley on my VT last nite along with NGK iridium plugs (1mm gap). wen it was done i started the car and it idled rough as if it was about to stall however i took it for a drove the engine got alot calmer and started to idle much better. it drove fine it didnt feel like it had much more power however i didnt expect it to as i know it takes a while for the engine to relearn and adjust. anywayz i went to start it 2day and immediately it stalled. tried again and it stalled. the 3rd time i tried, i kept the revs up for a short time and that prevented it from stalling. however the idle is still very rough and now the engine warning light has come on. can anybody help me??

maybe it could be the spark plugs....change them back over and see if that stops the problem, if its not that mayb its the ecu

just coz the plugs are new, dosnt mean there good. did you just remove the snout to change the pulley, or the whole blower?

put the old plugs back in , and see what happens.

its the only other thing you have changed.......


And yes, its takes a while for the full effects of the smaller pulley to take effect, You will enjoy when it does.......

Stick a y/t cold intake as well, not much$$$, sounds grouse, and works well......
