Help No Boost
 

Help
One minute I have boost the next minute I dont, it seems to come and go like the weather, it can be fine on one journey and gone the next!
I have connected the green plugs together an turned the ignition on just to test the solenoid which is clicking away nicely, if it was a pipe surely it would not be intermittent ? :wonder:

i had this when i first got car and put normal unleaded in it and its a uk 2000 model and standard..but when i eventualy run off the full tank of crap i put 97 in full boost within half a mile and never looked back since
