Finally got round to fitting my SARD FPR Yep, that's it running, revs out ok etc This morning the cold idle was all over the place, hunting up and down I opened the bonnet to see the pressure at 60psi so I turned it down to 40psi. Idle became normal and no further problems on the way to work This afternoon on the way home my idle went awol, I got home and the pressure was 20psi so I've adjusted it back up to 40psi What's going on? how do I make it constant
