hi....bit of a slight problem. ive got a 97 seat arosa..old car old engine. problem is car will suddenly slow down mid drive and accelerate very slowly, especially off the lights. also it struggles to pass 60mph, even on a flat road and will struggle to go up ANY incline past 20mph! need help guys as people behind me dislike the lack of speed benefit is that the car backfires even more when it does this

just joined had an arosa since summer have decided to turn it into a project
