LPG Conversion



LPG, The Money Saver Wrong. Maybe in the good old days but not so much any more. Why Not? 2 reasons. Firstly, the cost of LPG has increased. 2010 = 30p a litre. 2018 = 60p a litre. 2024 = £1.20 a litre If you take into account that LPG is 25% less efficient than...
Manually Retract The Clutch Actuator

It's more common on the 451 than the 450 and Roadster but it's possible for the clutch actuator to extend when removed from the car. Accidentally knocking it, moving it harshly or just being unlucky and BAM, the internal helper spring extends the clutch actuator rod....

The ESP cartridge on the 450 and Roadster can be annoying and tricky when you change the wheel.
No Throttle Response
I Have No Throttle Response 99% of the time I hear this, the alternator has just been changed and people are convinced they screwed something up during the fitting. Well, you did, we'll come back around to that in a bit. I Haven't Changed The Alternator Try cleaning...
