Hello,

My car has developed a strange misfire problem when the car is cold first thing in the morning accompanied with the eml/check engine light flashing.

It takes several minutes for it fire on all cylinders and the eml light goes out, but otherwise runs fine. It had new spark plugs 8000 miles ago.

Also, there is a vibration when the car is in reverse. It sounds like it is from a heat sheild, although that makes no sense why it only happens when the car is in reverse !!??

Any advice gladly recieved :)
