Need some help with fresh import

[juniort]

hi i have imported a black pulsar gtir totolly stock.....

car seem to missfire under load so i have replaced all plugs with ik22 and they are fully carbonised straight away..... so my problem is not solved i then tried to check each plug was sparking and it was...

i have used the search facility but cant seem to find the correct answers....so apoligies there.

symptons


idles funny
black smoke - under load
sounds like its missing..


what is the next stage for elimination, i have checked all earths and pipes too...

i have ordered a set of new leads for it and am hoping this might solve it.

would the AFM cause this problem or idle control valve... or distributor cap ?

again thanks for your time

You will need to do a fault code check to see if any sensors are malfunctioning like the air flow meter. You can also take a look at the ecu found at the centre of the footwell in the console area, check to see if it has been mapped by a tuning shop.

You can tell if the ht leads need changing if there is hesitation under load. One of the best investments you can get is buying the workshop manual for the car, thats if you do the work yourself.
