For any of the experienced tunners out there perhaps u could help. I have a 1993 WRX jap import, standard car but when accelerating (foot on floor) it gets to around 5000 revs then completely dies, rev counter just falls bak to 2000 rpm then it kicks back in????

I have used my mates wrx and swapped ecu, coilpaks, crank sender, fuel pump but problem still is there.

please help with ideas of what else to try.

Is it at 112mph? or is is really servere like hitting a brick wall?

Mark Bateson

Plugs ok, checked, boost solenoid how will this make diffrence?

speed doesnt matter as it is in any gear at roufley same revs. comes in severe like brickwall.

Sounds like it may be overboosting. Cleaning the solonoid may help.

Mark Bateson

not overboosting its only 9psi maximam

Mark, I had this on my '93 WRX import when i first bought it. It was definitely the plugs..i had one plug breaking down under load..very severe jolt at about 5500 rpm and then the revs would die. Changed the plugs for some better ones ( HKS if i remember correctly) and problem went away. Nothing untowards since.
