Has the lpg been recalibrated recently?
Yup
MAP pressure tweeked down to around 1.1 bar and gas map tweeked a couple of weeks ago.
Just had the Stag software running on it and everything is spot on with the exception of a few codes, all pointing towards voltage problems on lpg injectors accross both banks
The more and more I look at it, the more I am thinking voltage.
With the power amp added to the audio setup, that's going to pull volts away from the car systems too
Anyway, with all engine sensors requiring a stable voltage to make the engine properly and with the battery at least 4 years old to my knowledge, i've let Europarts relieve me of 45 quid for a new battery which hopefully is ariving tomorrow.
Not saying thats the cure but I know its not in the best of condition and its another thing out of the equation
Also just to clarify, the latest set of codes came with he car running on LPG and petrol
due the lack of LPG stations in darkest Lincolnshire
