Ford Mondeo ST220 - Lack of power and misfires
Hello,
I own this car for a few years, bought it at 220000 km (135000 miles) and it now shows 30000km more.
Issues:
- I feel like the car lacks some of its original 226 HP. The engine runs great but lacks torque under 4000 rpm, it shows good performance but high way speed tops at 230 kph instead of 250 kph? (143mph instead of 155).
- It burns a bit of oil, I need to check how much exactly.
- I have is a random misfire at low rpm (<2000rpm) when under high load.
- Fault Code P0443 randomly appearing (Evaporative emission system purge control valve circuit), I do not think it is related though.
I replaced:
- Ignition coil, with no success.
Considering the mileage of the car, I was thinking:
- worn out pistons rings?
- obstructed cat?
- valves seals?
I would like to check the cylinders pressures but I do not know what values I should get?
Thank you!
