Question about 1994 Subaru Impreza
U alright mate just wondered if you could help me out?
ive got a 94 import sti having trouble with it holding bac and bac firein when in hight boost!!
ive change the plugs but could it be the plug setting set to high for causin this problem?
Usualy when car is bac fireing its the leads or spark plugs, if u hav changed them, itl be a fuel problem i.e fuel pump fuel filter even injectors if there stock and you are runing over 20psi they will be peaking out. if not then the only thing left would be your boost solinoid. earlier models have a boost cut at 14.7psi if running stock ecu hope this helps.
