You need to Replace the Catalytic Converter. That is what you are Smelling. It has Clogged up and will also Cause the Light on the Dash Problem. Please Rate My Response! Thanks!

I had the same problem. Have it checked at an checkers with one of their computers. I had a multi misfiring. I changed the ignition module on it. It runs great now.

Hi LPG is very dependent apon plugs and lead quality, the first thing to do is replace them both with new, it may very well cure the fault.

Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

SOURCE: Engine light is blinking and it runs very rough/low power in gear.

Check the coil pack. Same symptoms on mine. It went at 74,000.
You can get the resistance specs from a shop manual. I have been told the plastic engine cover traps heat and makes short life of the coil pack. I removed the top engin cover, cosmetic only after replacing mine. You will probably need spark plugs also they are probably fowled by now. If you have not changed spark plug wires in awhile in would not hurt.
