300 EFI distributor control module ?
My 91 300 sometimes "bucks" at low rpm while accelrating. Does anyone think it could be the Distributor control module (mounted on the side of the dist) or do they just go bad and stop working altogether ?

Hate to go out and buy a $80-100 part to find out it aint the problem.

BEFORE you spend a cent, stroll down to your local Auto Zone/Advance Auto/ O'reilleys and ask them to pull the codes. They'll do it for free. You can even buy a code reader for 50-100 bucks and do it yourself.
I doubt the dizzy module is to blame; you'll just spend $$$$ until you know what code it's throwing.
Good luck.

X2. Pull the vacuum line off the EGR valve, plug the line, and see if the problem goes away. Make a restrictor plate if it fixes the problem and put the EGR vacuum line back on. It worked on my 300 EFI.

Hi Bill, good to see you again.
Has that E250 got OBDI? It will not tell you anything but "It works"/OR/ "It don't work (or is missing)". Even THAT is something to wrk with. You'll hafta do it the old way as above. How bout takin it off n see if that changes anything and what/where?
