i recently converted from gasoline to propane/gas, it now uses both. The problem i'm having, after installation i'm getting warning lights for i.e.; pos trac off, vsc off, check engine, all are lighted. I reset the computer the lights went off for a short period of time and are lit again. i need the pos trac to function because of conditions where i use the vehicle. is there a solution to have pos trac while using propane?

Need to Have the PCM scanned for the codes, this will help in diagnosing the problem with the TRAC and the engine management.

rescanned the pcm codes, the pcm does not recognize the propane fuel, and thus shuts down engine management resulting in the warning lights. my question is; is there a solution?
