Run fault codes and check for low pressure in fuel manifold, injector/s, coils and HT leads. have a compression test done to check for head gasket and valve problems.

Cylinder #1 misfire on a Ford Taurus SHO


Did you check the condition of the spark plug? If the plug is good do a compression check; a very low reading could indicate a sticking intake valve (sticking open). The easyest and cheapest way to fix a sticking valve is to introduce 1/2 can of Sea Foam into the air intake manafold; just follow the instructions on the can except you will use 1/2 can instead of 1/3 can. That Yamaha motor from what I have found collects tons of gunk on the valve stems. Good luck.
