Hey guys, so i have a 4th gen zc and i've had it for a while. Here's the problem so my idles bad im about to clean out my idle air control valve again after about 2 weeks. My dad just took the liberty of using my car while i was out of town recently and filled it up with unleaded and i noticed the the valve cover gasket is shot and its leaking oil. Here's what i dont understand earlier today i was going to pick up the gasket and started losing power bad, it felt like an electrical issue, and the check engine light was on of course and the ecu blinking. Also before all of these minor issues it would slightly cut off on me switching to second right when i would put it into gear. All the grounds are good and the battery is in the back with one cord going through the frame. If anyone could guess what i was experiencing through some similar experiences i'd appreciate it. Thanks.
