93 Dodge Dakota choking when idling and won't go over 25

The idle goes up and down even not hitting the gas. when you hit the gas it goes crazy. Could not find my other post

okay...you can and should retrieve diagnostic codes as recorded by the OBD-II system who's connector will be not three feet from the ignition on the bottom of the dash...might be a plug that says "diagnostic"~ for fifteen bucks you can buy a plug-in scanner~

these are just educated guesses here now...so no lawsuits with this info~ The EGR (exhaust gas recirculation) system introduces exhaust gas mostly nitrogen and unburned gasses into the manifold when the combustion temperature gets too HOT and also upon deceleration...supposed to be on DE-celleration...gets all clobberd with carbon and cannot switch fast enough...get's jammed and does not operate properly....disassemble the EGR valve...insure the solenoid connection that controls it is working properly and blast the valve free of carbon with some brake cleaner~

that'd slow you down to 45 max....on account you're givin' yourself a "dutch- oven"....in a sense~ cannot breathe....mostly exhaust gas....y'see...check the operation of the EGR valve....okay.....next probably item~

okay...the idle air control valve...gets full of varnish (from the gasoline) and should be replaced~ https://www.google.com/#q=93+Dodge+Dakota+idle+air+control+valve
