I'm running a 4.0ltr Cherokee with a Dutch gas conversion. Ran well for two years ten problem with the LPG. Gave it to a local "Jeep Specialist" who after 3 attempts not only cocked up the gas but also the petrol starting. It's OK in mild weather but cold starting is a pain. The service manual isn't helpful. Is it a tuning issue or has the cold start choke gone kaput?
Also can anyone direct me to a beginners guide to LPG servicing?
