I'm a new member so Hi All! I run ZT-T with a MGR LPG conversion. I occasionally get a serious misfire under hard acceleration which causes the engine Fault Light to come on. Its been on now for over a year. T4 shows no faults but says cats are running too cool or both banks running lean. MGR dealer says fault is LPG. LPG dealer says the opposite. The unusual thing is that when running on LPG the motor runs so much better when the weather is really hot. I can't quite explain why but I feel it might be a sticking gas injector on the LPG side and may be the hot wheather frees it up? Any ideas? Thanks and safe motoring to you all. Phil
