OK, i have done the reverse fuel rail thing FPR SET AT 3.5,,
oil catch can sorted,,
BUT now the car is hunting on tickover, ,

there is a small electrical conection under the manifold for the fuel something(small return pipe to tank) i just cut one pipe and blocked it (think to manifold) would this be the cause

any help appreciated

 

Thats your purge sol. One pipe goes to the tank,the other to the carbon canister.
The one that goes to the tank needs to be vented to atmosphere,the carbon caninster can be removed,with all pipes. The tiny pipe on the throttle body goes to the canister,and will need blanking off.
You'll need to leave the electrical connector on the purge sol,or you'll get a cel.
Check the electrical connectors and the earths that were disturbed.

 

THANKS (MIT) ill check that out in daylight
