HELP! my jeep is runnin RICH!

Hey new to the Jeep world, I have a 89 4 cyl 2.5L but I need help. She runs RICH I know this because it smells of gas when its cranked up, back fires when I shift into neutral at high speed, and it dies when I decelerate from a high speed... I need some help, any ideas are GREATLY apprectiated. Thanks in advance!

Have you checked the plugs and air filter, possable the float is allowing fuel to leak past, was shis a slow transition or did it just kinda start...

I would bet on the float either being set too high or the float needle not cutting the fuel flow off..could even be a piece of trash on the float needle

Get use to it, I put up quite afew question before that never got a response. As for your question. Have you done a full tune up? That includes plugs, wires, cap/rotor, fuel filter, air filter, O2 sensor. Check timing? Injector leaking by?

You need to post more information for us to being able to give you a decent answer. If not you will get normal answers like check the plugs and such. It's always good to change fuel filter and other cheap normal maintenance items.

Thanks guys, I apologize for the absence of details, yes I have done a full tune up, plugs, wires, cap & rotor, fuel Filter, air filter, oil change with filter as well... I have not checked timing, I'm assuming I need a timing light for that, maybe that is my next purchase... I'll keep ya posted!!
