list of things ive checked is as follows:

vac lines
compression perfect on all cylinders
spark plugs brand new gaped
spark plug leads brand new
distributor cap
swapped out dizzy and checked connector
swapped out coil and transistor and cleaned connectors - no difference
ECU swapped ecu with a shit one i had which ran perfect but wouldnt let the car rev over 3000 rpm - also same result
temp sensor under manifold and plug
fuel pressure regulator replaced with a brand new one - no difference
throttle body position sensor, replaced with 3 others all 3 same result, replaced the TPS plug cause it looked sus, no difference
checked injectors and tested in and out of car, under pressuremchecked wiring between all sensors and injectors ecu plug all came up good after changing the TPS plug
swapped out the airflow meter with a known working one from neighbors car - still the same result
****** replaced injectors still same result ******
replaced icv and checked and cleaned its plug - still the same
changed fuel filter no difference
replaced fuel pump made no difference
worth mentioning ive cleaned every plug while checking


last time i ran the car would have been about a month ago so dumped all old fuel and filled it with fresh 95 - before starting

ive run out of shit to check, any other suggestions ?
