Allright here's the deal. I had my upper intake off to change the valve cover gaskets and do some maintanence. I did a full tune up including the fuel filter. My torque wrench must be broke cause while I was torquing my upper manifold I tightened it a little too much and the front manifold bolt snapped in two. Would this cause a vacuum leak??? The car idles fine but misses once you get on the gas and while accelerating. I double checked the plug and plug wires and they are ok. I even did a cylinder balance test with my scan tool and it came out allright. I'm kinda stuck and pissed since I'm on leave with the military and will be leaving in a few days and my car will be staying here, I'm just trying to enjoy it while I'm here, but can't until I fix this! If anybody can help out I would appreciate it!
