Hi guys i have a dec 2000 mk4 golf 8v gti and recently it has been running very lumpy. i have replaced the lambada sensor recently and its always been serviced every year. checked plugs and leads and they seem fine, i took one of the injector leads off and there was no difference but when i took one of the other side it ran even worse so i now think i might have an injector problem. there is 140000 miles on my car and im lookin to sell it but i wouldnt sell it to someone with it running bad. do injectors have to carry same part numbers?
cheers
