Surging at constant speed in 93 Dodge spirit 2.5 L
We have changed the fuel filter distributor coil and oxygen sensor. The car originally
started it's issue only at 40-45 mph. When set on cruise or with foot feed. Now it does it
at any constant speed. There is a surge in power and shaking that only goes away when
applying gas or letting decelerate.
There are some adjustments that you can do on the cables. The cables may have stretched and just need a fine tune adjustment or replacement. The other ideas are the throttle body needs a good cleaning, throttle position sensor, or air control valve. If possible give a scan for pending or stored codes. On older vehicles you have to do a jumper wire underneath the dash to retrieve codes. I don't miss that :D Good Luck!
