Over the last few days my cars been juddering and misfiring when its below 3000rpm. At first it just felt like a flat spot in 5th at around 2500, but this morning it would not drive smoothly at any throttle position below 3000rpm in any gear.
The fuel was low (ish, see separate string) so after about 20 miles I filled up with Optimax and the problem seemed to go away.
I used to do short journeys in the car but Ive recently started doing long journeys to and from work every day.
It had a major service earlier this year, so I dont think it should be the ignition components or filters or anything. Are these worth changing anyway?
I really didnt like the sound of it, I didnt think I was going to make it to work (oh no), but genuinely Im worried about my poor old Clio, has it just developed a taste for decent petrol or is there something more serious happening?
