I HAVE A 99 WRX WITH ONLY 18000 MILES ON THE CLOCK
IF I DRIVE THE CAR STEADY IT WILL RUN PERFECT.
IF I DRIVE THE CAR HARD AT AROUNG 5000 RPM THE ENGINE WILL MISS
A BEAT ONCE AND THEN CONTINUE ROUND TO 7000RPM
THIS HAPPENS IN 3RD 4TH AND FIFTH.
I HAVE CHANGED THE PLUGS BUT THE PROBLEM REMAINS.

ANY IDEAS

CHEERS

I cant help myself but a lot of good guys on here so keep trying.
Best of luck try Power Engineering they know what they are doing.
