I posted this yesterday but think I posted it in the wrong place cos I'm daft like that. Apologies for the repost if it's not allowed! Hi, new to all this and not very technical so be gentle with me...! Had this car since Jan but recently it has started to cough and shudder on motorways when the rev counter hits 3000, effectively limiting me to 60-65 mph which means I get stuck behind lorries a lot. I've had it serviced and a new coil pack fitted but it's still the same, can anyone shed any light on this for me? Cheers Lisa Edit: should mention it's a 1.8 manual petrol.
