I-- ... does anyone know what there for ... ... any help is appreciated

Check the MAP senor hose at both ends for looseness or split. I had a similar prob and was a split in hose to vacuum, in my case probably caused by a backfire??? Maybe not but happened around the same time.

One of your stray plugs sounds like coolant level connector which you may or may not have in your header tank.

i have the coolant level sensor connected .. but thats the part of the loom that the "T" shaped plug is on .. and the map sensor and hose has just bee replaced ... not that long ago .. i had drammas with the car a couple of months ago and did everything from cleaning of the dirt around the lip of the exh to rebuilding the motor ... i will double check it tho ... you never know ... computerised cars ....

Have you done a self test on the ECU?

yep ... comes up with code 11 ... system pass ,... but i dont know if u can believe that half the time ... can you ???
