'99 T plate Impreza Turbo, Richard Burns 5-dr limited ed.

Continual Misfire that isn't:

Plugs
Fuel Filter
Injectors.

As soon as the turbo cuts in it's like a rev limiter coming on. About 3000 rpm, does it when stationary as well.

Any thoughts/sugesstions?

I think i've heard about this one before. Have you looked in the technical forums?

:(

Get the car on a select monitor or delta dash to check error codes.

Could be the coil packs, or a sensor gone

Could be overboost and the ecu cutting the boost level

plug LEADS???

is the speedo working OK?

It's not the fuel cut if it is doing it when stationary.

I had a similar problem, for months, on a car the same age as yours. Car would be driving along fine - and then big misfire - and actually in the dark - the lights went off as well!

The solution....well I changed everything - and did not solve it.

But then a revelation - I did the earthing mod - new earth cables to body, manifold and block. What a transformtion - no misfire - and for icing on the cake earthed the ECU and alternator. Car runs MUCH better and the radio sounds better (when I can hear it!)

Sorted.

Trout :D
