Wont idle under load? - Pirate4x4.Com : 4x4 and Off-Road Forum

i have a 4.3l vortec engine that i just switched over to propane and having some problems getting it to idle. Finally got the engine to idle around 1200-1500 rpm's but when i shift out of park or neutral and put a load on the engine the rpm's drop down to 500 rpm's and the engine dies. I have turned the idle up to about 2000 rpm's and still have the same problem under load, but it doesnt die on me. any thoughts?

Sounds like your starving for fuel.
