I have a Ford Fiesta 2010 Diesel 1.4. Recently the car has been struggle to accelerate when the gas pedal is being pressed. The engine still roars and the indicator will shoot up, but the car just over revs. If I press the gas pedal really gradually and slowly then it's fine, but the moment I put any normal amount of pressure it will over rev so I have to lift off and re apply pressure to the gas to drive properly. Couple things if it helps (1) Once i'm over 70 it doesn't happen much. I can put my foot down and the car will speed up as normal and (2) The car has not been serviced for just over a year. So yes I know I need to get this done asap, but not sure if this would be related? I do not know much about cars so don't want to go to any old mechanic and get conned so wanted to get a bit of an idea what it might be? Thank you!!

Welcome to Motor Vehicle Maintenance & Repair! Does the car have an automatic or manual transmission? How many miles on the Fiesta?– Pᴀᴜʟsᴛᴇʀ2 ♦Commented May 27, 2018 at 18:27

could it be the lack of service i.e. blocked air filter?– NoumanCommented May 27, 2018 at 19:37

1From your description, it sounds like the clutch is slipping. In a manual transmission car, there is direct power going from the engine, through the transmission, to the drive wheels. There should be a linear curve between the engine and vehicle acceleration. There's only two places which might be in question here: the clutch and the tires. I really doubt you're burning rubber until you reach 70.– Pᴀᴜʟsᴛᴇʀ2 ♦Commented May 27, 2018 at 19:44

Based on your description and assuming you have a manual tranmission car, it looks like your clutch is worn out and slipping. Driving like this with an over-revving engine and a slipping clutch will only make things worse and more expensive to fix because other parts will now wear out and fail too. Get your clutch replaced ASAP.

Sorry for the delay in replying. Had it checked out. The injector seals were leaking/broken which was leaking causing the loss in power– NoumanCommented Jun 20, 2018 at 11:53

1I must say I was incorrect. While the leaking seals seem to fix the issue very temporarily, I did have to end up changing the clutch. You were correct! mechanics.stackexchange.com/questions/57688/… if you're interested– NoumanCommented Aug 6, 2018 at 20:56
