Having problems with your 1985 Jeep Cherokee ?

The engine turns on but dosent hold an idle

\015 I have a 1985 jeep cherokee with a 2.8li and a four barrel carb. the carb is rebuilt and the fuel pump is new. the engine dosn't hold an idle unless i half cover the intake. it's draw ing too much air and not mixing gas. i think? the mounting gasket i got from auto zone is very thick. is it ment to completely replace the old one? if so how do i remove the sensor that is on the old one and how do i reatach it? is there a sensor that might have failed?\015 Posted / edited by AnonymousUser on : 28-05-2018

Answers :

That year car doesn't have a lot of computer control of air mixture like newer cars do so i would look for the butterfly of that carb to be letting too much air thru while idleing. If just rebuilt did the butterfly get cleaned good? Is there a build up of deposits around the ends of it? This will let air thru and cause the problem you describe. Happened to me on a 1985 Toyota. If this helps please reply cause ithelps me continue to answer questions here and good luck
