2000 740, sputter, shutter, not smooth like butter
So I posted once and seem to have gotten no replies and lost thread.
So I am asking for help again,
Around 20 - 30 mph at a slow acceleration the car will start to shutter, sputter and just seems t be missing. I have ran BG 44k trough the engine with a full tank of gas and it is now at the bottom 1/4 of the tank and seems to be as bad as it was.
It did seem that with the gas tank in the middle stages of the tank it ran better. Doubt it has anything to do with it but seems to be that way.
So, no check engine lights on, no warning lights. Engine runs strong so no a compression problem.
I am going to check for a cracked spark plug and have a master tech run a diagnostic on it tomorrow but wanted to see if anyone has seen this before.
New mass air flow sensor and new rear main seal, not sure if this helps but these were done 10k ago. Miles are 205,000.
Stresssssssed out and sputtering
