|ChiroSean||Thanks. Some people told me to check the O2 sensor, MAP sensor, and MAF sensor. Also they said that changing the engine oil to fresh oil before I take it back for another test might help. I also found a vacuum line up near the passenger side fire wall that I can not find a place where it would go??? My jeep doesn't have AC or cruise control or anything so, not sure where it would go. Any suggestions? Thanks again.|

Need Help! 94 YJ won't pass emissions
I just bought my first Jeep and can't get it to pas the clean air check here in Indiana. After the first test I changed the plugs, wires, cap and rotor, and repaired the vacuum line between the air box and the PCV. I took it back and had it tested again today and it failed worse than the first time. The hydrocarbons and CO levels are much higher now. I looked at several sites online and there a ton of suggestions, but I thought I would look for some more Jeep specific info if anyone has had similar problems. My Jeep is a 2.5L with a % speed manual trans. Thanks. Also what should the normal operating temp be? Mine runs at or just above 210. Do I need a new thermostat or just flush the cooling system? thanks!!!
