I have an 86' 190E 2.3 8v, and seem to have problems with power and acceleration. If I stomp on the gas, the car would accelerate slowly, but if I let up 1/4 off the petal, I accelerate much faster. Also, my car seems to have trouble accelerating until after around 3000 rpms where the power seems to kick right in. Do I have a problem with the fuel injection? Is it something I need to adjust? Any help would be awesome. Thanks,
Peter V.
