FRST Map Sensor Problem?
My car will start fine, run ok ish but requires a light bit of throttle to get it started and keep it going. If you take your foot off the accelerator it will sometimes just idle for a minute before cutting out but most times it will just cut out.
It will rev fine in negitive pressure but as soon as it hits 0 on the boost guage it just goes to die. Interestingly it does this with the boost hose disconnected too, ie running as n/a!
I think its running slightly rich.
Does this sound like a MAP sensor problem? Ive disconnected every other sensor which has had a detromental effect to the engine running HOWEVER when I disconnect the map sensor and block its vacume feed to the engine the engine still runs as above. Disconnecting the map sensor has no effect at all! Which seems a tad strange. Surely the map is faulty? (or wiring)
Any help muchly appreciated as always.
