95 dodge fails emissions at the low speed apx. 25 mph what is a common problem

There is an ABS wheel speed sensor located in the rear differential.
If this fails it affects the ABS and may cause your speedometer to read erroneously at speeds under 25-30 mph. There is also a VSS located in automatic transmission housing. Manual trans vehicles don't have this. They use engine rpm to determine speed as there is supposedly no slippage in the manual drive train.

You can test it with a vacuum pump

I would be say if new spark plugs,new air
filter,new or clean rotor & cap,synthetic oil,don't take care
of it,you will need a new converter

Don't forget the oxygen sensor may be old as well

Clean out all leaves & dirt between the condenser
& radiator & make sure it doesn't over heat

The converter may be blocked as well as worn out

Improper Ignition Timing

Defective Ignition Components
(ignition coil/s, distributor*, distributor cap*, distributor rotor*, ignition wires, and spark plugs - NOTE:*Distributor-less engines do not have these components)

Lean Fuel Mixture

Defective Catalytic Converter
(Some symptoms of a bad catalytic converter:
Major loss of power over 15-25 mph.(does this speed sound familiar to you?)
Strong sulfer or rotten egg smell emitting from the exhaust.
Loud rattle being heard from inside the catalytic converter.

Defective Air Injection Components

Faulty smog pump if fitted.

Low Cylinder Compression.

get your injectors cleaned. change the air filter .change your plugs. put a fuel cleaner in your fuel tank.

It does have an EGR valve

The speed sensor that controls the speedometer is located in the top of the rear differential housing, this is your most likely problem and is very common with this vehicle. Being that it is a direct input to the ABS module it will cause those indicators to illuminate when the sensor fails.

well your tranny is slipping check your tranny fluid make sure its not low on fluid

sounds like the speed sensors. there are 2 of them. High and low speed. run about $20 each and are VERY common on dodge's. if you get a code 25 that is the problem.

check your brakes on that wheel. The caliper may not be releasing
