I have one cylinder that loads up at low RPM.
Climbing a hill on hwy I'm now looseing speed.
Ideal is rough and sometimes dies.

Could these things be caused by head gasket or vaccum leak?

Thank Jan

Engine running rough or misfiring can be cause by the following:
1.Defective spark plug.
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
7.Contaminated fuel.
8.EGR valve that is leaking.
