When torqing, I used a middle to back to front/side to side pattern...let it sit for a half hour and then did a 90 degree torqe again. I installed a Mahle gasket that says its "torqe too hard resistant"
All of the coils are tight and connectors pushed on properly. When I fired the car up, it idles very rough and the 4X4, service engine soon light and several others are on. If I bring it up to 2-3K RPM it smooths out. As soon as I bring it down to idle, it runs rough again.
FYI, I changed the gasket because it was leaking onto the exhaust and smoking really bad, however the car itself ran great...until now.
Any help would be greatly appreciated.
Thanks!
