15mpg

i thought there was something going wrong over the last couple of months, after only getting 38mpg around town, today it dropped to 27 miles to a tenner, it started to missfire bad, i had to drop it into 2nd gear and keep the revs up to get home, i'd already changed the fpr, but looking at the fuel pressure guage it was reading 60psi

, so i had the ball ache of changing the rail yet again, on doing so the fuel pressure has dropped to 37psi

, i'll see how it goes on fuel now.

lol the fuel pressure regulator has to be one of the most common things to go on the s12.

really does suck to change it too, glad I have an FSE to go on

Mine has very similar symptoms and since I put the new head on it doesn't like to tick over, I thought it was a dodgy injector I now wondering if it's the fuel pressure regulator.

So fitting something like This or This may cure the problem?
