Hi all, my st is only boosting to quarter, think its my boost soilenoid, when I pull the kam fuse out for half hour it boosts probley again, surley if the soilenoid was broke it would still be broke after taking fuse out and putting back in, ??? Does this mean my boost soilenoid is ok ? Cus it boost after leaving the fuse out 4 a bit ? Any advice thanks in advance .
