currently have a vectra 1.8 petrol which is misfiring from inlet manifold at about 2000 revs get past this its okay, it improves when warm. Currenly relplace MAF, canister purge valve , dis pack, removed egr valve and it is working checked for leaks checked pipes etc, cleaned throttle and hole resealed gasket with no avail, still same problem. i did the paperclip test and faults were 0443 tank vent valve which i replaced 0100 maf which i also replaced 0110, 1405 egr. blanked this no joy 0135 and 0130 o2 sensor, also replaced, i have also done the yellow wire earth mod no joy.
i have reset ecu but same faults occur.
This is really taking its toll on me and have tried everything any ideas ?
Ecu light is on and off at the mo but no new faults stored and car not driveable due to misfire
