go to autozone or advance auto and ask them to check your codes with a code scanner. its a free service they have. If you have a power programmer you could use that also to pull codes.

An individual ignition coil (1) is used for each spark plug. The coil fits into machined holes in the cylinder head. A mounting stud/nut (3) secures each coil to the top of the intake manifold . The bottom of the coil is equipped with a rubber boot to seal the spark plug to the coil. Inside each rubber boot is a spring. The spring is used for a mechanical contact between the coil and the top of the spark plug. These rubber boots and springs are a permanent part of the coil and are not serviced separately. An O-ring is used to seal the coil at the opening into the cylinder head.

1.Depending on which coil is being removed, the throttle body air intake tube or intake box may need to be removed to gain access to coil.
2.Disconnect electrical connector (2) from coil by pushing downward on release lock on top of connector and pull connector from coil.
3.Clean area at base of coil with compressed air before removal.
4.Remove coil mounting nut (3) from mounting stud.
5.Carefully pull up coil from cylinder head opening with a slight twisting action.
6.Remove coil from vehicle.
