Nissan Almera 2005 115000 miles
My car does not accelerate, it loses power instead. It has been checked with three different scanners but no failure was indicated. I've checked the fuel pressure and it is 48 pounds. I've changed the positions of the camshaft and crankshaft sensors as they are the same, I've cleaned the injectors, the throttle body, the MAF sensor, but the car is still the same. Has anyone had this problem? I have my doubts with the VVT valve as, if it fails, it is not detected by the ECU and it affects the engine time and performance.
