  post locked   DODE RAM 91 IDLE POORLY  

Hey maybe you guys can help me.... bare with me ... I just recently cleaned the CARB ON MY DODGE RAM 91 3.9l v6 and it was running like a champ ... so I was feeling good and decided to get a new oxygen sensor since my carb was clean and to get a good reading ... went to the car parts store and the guy sold me a generic one , well that’s when things started , at idle it almost chokes out and then it revs up and starts the loop again , changed the throttle position sensor for a new one , also took a look at the map sensor and it seems to work and also gave a clean up on the idle position sensor ( it looks like a solenoid with a bolt head coming out )now after all that when my throttle position sensor is connected and I disconnect the map sensor vacuum hose the problem is mitigated a little and runs a bit smoother but if I disconnect the throttle position sensor and re connect the map sensor vacuum hose it runs good again . So to summarize, is this because the oxygen sensor is not the right one ( I connected the cables identical to all the installation guides I could find on the net) or is this some other problem ? I would hate to go get a original part for no reason (generic cost 250 pesos (I live in Mexico) but the original is something like 800 pesos) please if any body has an idea please share.
