ive bought code readers and tps adjustment lights and a whole whack of everything. its overfueling very badly. i replaced the injectors this fall. it has apexi turbo timer and turbosmart boost controller. the engine has 6000kms on it since a rebuild. it has a test pipe in place of cat. it runs fine at idle and if you rev it up theres no problem but when your driving it bucks and pops at anything from 2000rpm to redline. sometimes it lets you go any rpm you want and sometimes its scary how bad it runs.Im sick of shady mechanics who dont know rotary from piston. Im looking for someone who knows their **** to help me out in a big bind. Thanks for everything

it either timing or a vacume leak

get an inductive timing light and check ur timing if its set correctly search for a vacume leak and dont be afraid to pull the uim off to get a good veiw of ever thing

if its only a part throttle thing, id look for a bad o2 sensor



if its all the time, maybe a bad afm?
