OK OK here it is. I have a 90 xj 4.0 that is a big prob. The jeep ran good when i bought it, 2 weeks later the idle goes south and starts running realy bad. i replaced plugs and wires cap and rotar and it still runs like donkey dung. I had the coil tested and had to replace the ignition control module. it sometimes idles at about 1000 rpm's and it most times idels at 2500-5000 rpm's. The tb is clean and i have replaced the air injection valve. Their is a distinct smell of raw fuel out the exhaust and it spuders on steady driving. when you step ont the gas it runs like a champ but normal driving is horible.Idle is realy ruff to. anyone with tech help would be apreciated.
