01 E53 4.4 Acceleration hesitation

Hi folks,
My 2001 E53 4.4 is experiencing some acceleration hesitations at around 2000 rpm. The hesitation stops if I decelerate or accelerate. Moreover, there is no hesitation when I drive in sport mode, but we all know how much gas getting sucked in sport mode.

I have changed my spark plugs and check for oil leak. There was none.

I need help because this is really annoying.

Thanks

Hey jmr3, this is how you troubleshoot it. Drive your X5 in Sport mode (pushing your speed shifter to the left). If you don't feel the hesitation, it is FOR SURE your torque converter. I will tell you this one thing: If it is your TC, replace it as soon as you can. It will create more issue for your transmission and four time the expense if not fixed.

I learned the hard way by procrastinating on mine, and it messed up my transmission after sometimes. I got ride of my X5 because of that bad transmission.

Well I guess I got lucky. I took it to my very experienced wrench and he said it didn't sound like a torque converter issue to him and, fortunately it was just some cam sensor issues.

A little background though. My 01 only has 56k (a bit light for a tc issue). Recently I had "lean condition" check engine lights and replaced the Mass Air Sensor. My wrench also found cam sensor codes so we did 2 of those.

When he went to check it this time there was no check engine light, but there was a cam sensor code of some type. He got 2 new Bosch cam sensors, replaced them, and everything is fine. He disclosed that the cam sensors he first used were an off brand and he thinks they were bad.

Covered it all under his warranty.

TRY CLEANING YOUR MAFS AND YOUR CRANK SENSOR GO BUY A CAN OF CRC MAF CLEANERS AND USE IT ON BOTH THERE ARE VIDEOS ON YOUTUBE ON HOW TO DO IT.
ITS CHEAP AND WONT TAKE LONG IF YOUD LIKE YOU CAN ALSO LOOK INTO THE THROTTLE BODY SEE IF THERE IS OIL OR ANY RESIDUE IF THERE IS SPRAY A CONTROLLED AMOUNT OF CRC IN THERE AND TAKE YOUR TOOTHBRUSH AND SCRUB DONT SPRAY TO MUCH INSIDE AS IT MAY BE DIFFICULT TO START IT UP. THIS WILL TUNE UP YOUR INTAKE SYSTEM YOUR CRANK POSITION SENSOR IS LOCATED RIGHT BEHIND YOUR CRANK PULLY SPRAY AND CLEAN NOTE IT COUNTS TEETH ON PULLEY AND NORMALLY GET OILY...RMBR ENGINE MISFIRES THROW UP A ENGINE CODE RIGHT AWAY SO ITS PROBABLY NOT COILS OR PLUGS. GOODLUCK
