Might be time to change plugs.Use NGK V Grooves.Also could be that you have not run on petrol for a while?Gas is a smoother running fuel than petrol and an engine must run on petrol correctly before tuning gas.Check that H/T leads and distributor are in a good servicable condition.Make sure you have no engine vacuum leaks.Let me know how you go and if you need further help.I fit and repair LPG vehicles on a daily basis.

What problem could be causing the engine to run rough and uneven (hesitates) when cold? After few minutes running, it works perfectly smooth.


Petrol or Diesel? If petrol it's probably engine coolant temperature sender and if diesel it could be a defective glow plug or cold start device/pump timing.How you had glow plug draw test done?Is there any smoke and if so what colour?
