boost problems
 

hi can any 1help, when i drive my subaru its seems to loose boost more so when hot its as if its got turbo lag :cry:i have check all the pipes 4splits and found no faults could it b fuel starv?boost solenoid ,its a 1999 turbo awd wagon i was told that it was standard apart from de cat pipe but i dont think it is.when u first put ur foot down hard in 3rd it pulls like a train then shifted to 4th it seems to have a flat spot then if u take it easy 4 abit and then put ur foot down again it is ok 4 a sort time then reverts bk to having flat spot:wonder:

Have you checked for fault codes?

as above and also could be the boost solenoid if you haven't checked, I had a dip of about 0.2 bar at 5,600 which was the issue.

i haven't had a fault code done,should the solenoid click when ignition is turned on and off?and would it make a difference if i ran it on normal 95 ron unleaded

Ok have a search on here for fault codes, it'll tell you how to retrieve fault codes yourself. It's a bit long winded for me to type. And you'll get a list of codes. Clear them all out go for a good drive. See what comes back. Let us know.

I would check fault codes as above but also running on the 95 ron may affect it especially if it has been mapped on 99ron or v-power..

I've cleared the ecu of codes with the green and black plugs, and it said that the engine check light will flash half second intervals which it did along with a even shorter flash at the end is this a error?? i also cleaned out the boost solenoid at work today and it had black dirt in it i also checked it across a 12volt battery to c if it was working it was ok.Im going to have a long drive now to c if its any better will let u know cheers guy,Dan

Thanks guys, bin 4 long drive and its a differant car:notworthy
