Having an issue with a couple codes and looking for information and advice. Do not have a code listing for troubleshooting but would like one if anyone can send. So far for we found out the E38 has to do with the LP system. We did heat the engine up and drain the LP convertor of tar got maybe a thimble full. After starting the engine we now have an E-36 code? Not sure how to proceed next. If anyone can send parts pages for the LP system, troubleshooting sections from the manual w/code info I would be grateful. Thanks
