Our 1989 E190 2.6 has a bad stumble off the line if you try to accelerate quickly from a stoplight.The mileage seems to be really lousy also- even the economy gauge goes into red while idling in drive. poof of black smoke also leads me to think it is running way too rich , at least at idle. Also noticed some coolant under front of car. Any suggestions or can someone point me to good benz mechanic in west florida.

You could have a faulty fuel pressure regulator.</P>


Classic symptoms : black smoke, bad mpg, severe hesitation on acceleration from stop (due to flooding; FPR diaphragm siezed causing high fuel pressure).</P>


Have it checked out.</P></TD></TR>
