Hi guys from the sunny Caribbean (Dominican Republic)! I'm a proud owner of one of this old ladies. I have it since six month ago and my truck has a double fuel system... It works with LPG like Australian style, and of course gasoline (petrol for the Australians mattes)... Well, the gasoline system, wasn't working since I have it... I took the risk to start to replace logical pieces to realive the main fuel system... I bought the last week a fuel pump and AFM sensor, I installed today and works at least, BUUT... It has a problem to keep the IDDLE (going down to 400 RPM) stumbling, with a poor combustion and running rich... I need to say that with LPG runs great, normal, nothing compares with gasoline, no stumble, no poor IDDLE no nothing, I know that this will be a long road (and expensive as f*CK) to have an ok truck, but, I'm in the river and must to swim... What could be the problem? What I need to recheck? Thanks a lot guys!
