mk2 polo 3f conversion problems

[steveo3002]

fitted mpi fuel inj from a mk2f into my mk2 , cant seem to get it sorted



suffers from a bad idle,bit bumpy pop pop sound and refuses to start hot - between 3-20 mins , will start with bts undone , drives fairly okay above idle

a few things ive tried /done

timing set as per the book
air bypass mixtured tired various settings ...its set to 14.1 afr via a wideband gauge at the moment
tried another dizzy /cap/arm
tried another coil
correct plugs fitted
earths good
tried another tps
no obvious air leaks + charcoal can deleted
correct 3 bar pump fitted
new genuine blue sender plus tried others i had laying around
spare set of used inj tried with new o rings
spare afm tried
blocked the isv at the tb elbow- no change in running

engine basics should be fine as ive had the car driving for 2 years on a carb ..ive not touched the internals since

has crude diagnostics , no codes showing

still waiting on a ecu to try...them im pretty much out of ideas , anyone localish to cambridge that knows these , or a garage that remembers old cars , none of the garages ive spoke to have any ideas and dont really work on old toot
