Check the MAP sensor reading with key on engine off. It should be around 99kPa. With the engine running you want to see around 37 to 42. If it is high, you could have carbon build up on the valves or pistons. The other fault could be worn timing chain.

U need to have the engine scoped this will test all the cylinders for the proper patterns. Also check that all the wiring to the coils for power and ground are working properly. Use a test light or meter to test the power and ground wires on the coil.
