90 xj running rough PLZ HELP!!!!!
Hey guys just did the valve cover gasket on my 90 cherokee and in the process i broke the vacuum switch for the heater. Now the jeep runs rough as hell like its mising. Would this switch cause the jeep to do this or where should i start?? any help would be appreciated!! Also just installed the spectre 9945 intake and no problems after that. Drove to parts store and got the gasket did the gasket put it all back together minus the heater switch and it started runnin rough as crap likes it's missing. Will be doin plugs today after work but it was running fine before I did the valve cover gasket! Please help

Well sprayed the whole thing down and still no luck. It does sound like it's trying to pull a lot more air than before? Maybe that's it. Any input will help

With out knowing exactly what you removed to do the gasket theres no way to tell what been affected ? Changing a cover gasket has know effect on running condition.
