Hi all, I have a 51 plate 90' full size big intercooler, IRB remap and over boost box, single box stainless exhaust, egr removed,
Anyhow, up to recently its been running fine, I was going on a long run the other week soni gave it a drink of wynns injector cleaner as a treat ( no problems at this point )
During this trip It started to sort of misfire, it hesitates and usually "clears" then revs through fine, it seems to be getting there most of the time now, the misfire is not worse but defo more frequent,
I changed the injector loom about 2 years ago for the usual reasons, I have rechecked this and all clean, it has a ecu extender loom fitted also about 3 years ago with no issues, the ecu now sits behind the drivers head rest, changed the fuel filter a cople of days ago also, oil smells fine of the dip stick, and no coolant loss, doesn't appear to smoke any more or less than norm ,
fuel usage seems norm ( quite bad :0) )
So where shall I go from here please ??
