Hi everyone ive got a code up which i thought i would have solved with new coil pack, leads and plugs yet i havnt and it is still up and i have very rough idle. revs bounce. if i rev the car the revs dip to nearly 300rpm and it sounds like its going to stall but somehow the ecu saves it (this is at standstill). ive stuck some cleaner in it so should i see improvements immediately or does it take a tank full?
is there anything else i should be checking?
