ie brown,green,pink,or
(black turbo ones)its a 92 rev2 gti 3gse
dont no what colour mine are cant see them with out stripping it down.
looks like i have a sticking injector.
i once fitted injectors from a 24v 520i in to my 88 325i 12v e30
the 520i ones had a very slightly higher flow rate with a better spay pattern.
meaning the fuel combusted quicker.and it gave good results.
with out making it rich because the ecu controled the amount of fuel to then.thanks for your time
