Poorly 2.8i

Post by markyboy »

More info from the previous post, I took the warm up regulator apart and apart from a small bit of dirt and some minor corrosion all seemed in order. The engine fires up easily when cold but doesn't idle smoothly, the left bank runs a lot worse. There's a hissing from the regulator which stops when the engine is warm which is when the engine stalls. It won't restart until it cools down. I disconnected the vacuum hose while it was running and the revs rose so it appears the vacuum is good. Nothing seems loose or leaking so I'm presuming it's something in the fuel system which is giving too much fuel when warm but why does the left bank suffer more? Any ideas please.
