Has anyone got any idea what would cause sudden over fueling. Have had no problem using the M48 on closed loop after dyno mapping over the last 9 months, however over the last month had to replace plugs as they have been fouling constantly ecu doesn't show any errors, change the TPS, plug leads etc. is it possible one of the other sensors is causing the problem but no showing an error or perhaps a fuel pressure issue? Anyone got any idea what could cause the problem.
