I have an 85 325e, when accelerating the car seems to accelerate
sluggishly. I push the pedal all the way to the floor and some times it
will accelerate ok.

I thought maybe gas. I changed the fuel filter and the spark plugs. No
change. I'm thinking now I need a manual to try and figure out the
problem.

Help, I hope the motors not gone. It's strong when it is running, but
now it seems to have no power sometimes.
