I recently brought a 95 Subaru impreza 1.6 ltr 5 speed manual. I put my foot down on accelerator and it spits and splutters. If i put my foot down slowly I can get up to speed, but once I'm at say 100 or 110 kph every minute or so it starts to die down. I take my foot off and re-apply slowly. It slowly picks up but happens every minute or so. I have changed plugs, air filter leads and fuel filter.
Please help me.
