Hi i have a 1993 twin turbo which i have recently bought. Sometimes the second turbo boosts at about 4500rpm and some times it just doesnt boost for a while and then it will be ok again. The weather has been quite warm recently, could that make it do this. There is also some sort of electrical wire touching the floor from the engine bay could this be the problem. Any sugestions will be very much appreciated.
thanks danny

 

hi danny welcome to the board, this been your first post, we need more info to help you.
Does the boost problem only happen in certain gears,,, or when u going up the box driving hard. Also a picture of the wire in question will help us to answer that suspected issue.
(hot weather and under bonnet tempratures may be causing a sticking solenoid??)
