Hey guys trying to find out if anyone has or had a similar problem. When I try to speed up car feels like something is blocking or stopping the acceleration. I changed the mass air flow sensor, put new filters , changed the throttle position sensor and still nothing. I am due for an oil change in about 1500 miles but I doubt that's the problem. Any clues what it might be ?

 

It could be "crank sensor/cam sensor/coils/spark plugs/fuel pump/fuel pump relay",

did you do any kind diagnose....??

ZAYED,,

 

yes the spark plugs and ignition coils are good

 

Unplug battery for bit. If that doesn't work Google e55 ecu reset. I believe it's a few topics up on the Feed line .
