hi people,
have a prob with my 99 wrx wagon i need some help with,

when under boost between 4-5000 revs the car goes crazy,surging,backfiring just turns into a pig basically then after 5000 revs it comes rite again.

has anyone come across this problem and does anyone no a remedy.
would be greatly appreciated

 

not fuel cut by any chance from over boosting? you could try a search on here using the search function across the orange bar...
