My 300 Cu. In. Ford engine runs on propane. While I was going up a hill and on the freeway the other day it had significantly less power than previously. I changed the intake manifold gasket because it looked cracked. There is a Clifford head on the engine (I don't know if that makes any difference). If I stand on the gas pedal, the engine doesn't get any more gas than normal. I also checked the throttle linkage and that was fine and tight. I also had the transmission guys check out the tranny and it's fine also.
The system is only about 2 months old, so I don't think anything should go wrong with it...help?

Propane vehicles tend to burn valves, so a compression check may pinpoint your problem. You may also have a computer or a sensor problem.

Check the compression.

I found you have to change the timing and you have to sacrifice performance. For better performance change your compression ratio.

Simple really
Propane doesn't have the same BTU's per unit volumn as gasoline.
