Any ideas on why my 96 wrx mite missfire \ backfire on hard acceleraction (still pulls hard but cuts in and out) Running it on 96 grade fuel ,installed new plugs (ngk BKR6EIX) runs fine other than that ,sometimes small backfire between gear changes at less than 4000 rpm. engine type EJ20GDW5PE
thanks

Do you have a manual boost controller (mbc) installed? I have a 96 WRX and had the same problem and so took out the MBC. It now runs sweet. If you don't have one check the vacuum hoses from the turbo to the wastegate and also to the boost control solenoid, make sure they are tightened with cable ties or a hose clamp. Also could be your spark plugs make sure you have iridium ones, they out perform any others.

Hi,
Fault codes as follows
45
Pressure Sensor Duty Solenoid (Turbo Models)
42
Idle Switch or Circuit
Those are the correct codes for a Subaru.
good luck
Dan
SOURCE: 96 impreza wrx sti keeps on spluttering when accelerating
does it idle and rev fine when stationary but holds back when accelerating is so 1 of the coils is breaking down. simply find out what 1 it is and replace it
SOURCE: how do i replace starter on my wrx sti?
Disconnect the battery..
Disconnect the wires on the starter..
Should be 2 bolts that hold the starter in place - remove them and pull the starter out..
The new one will only go in one way so you cant mess it up..
Rate well ;o)

Does it only happen when you accelerate hard from a stop (or when moving very slowly)?
First, is it turbo'd? if so, how many pounds of boost are you running. If you are running high boost, how much is you spark timming retarded?
Does the exhaust smell like fuel?
