Hi Team
Help me before i light my Isuzu on fire lol
OK have a 1992 isuzu big horn 3.1 v6 irmscher rs was driving mint but one day it started loosing power and started to cough, splutter, back fire , and a shit load of smoke. took it to the first mechanic he put a o2 senor,plugs,leads,fuel filter,injector cleaner through and that fixed the smoke but still back fires and used a tone of gas. took it back to him but he said that's all he could think of. so took it to number two mechanic he said he had one with the same problem and it was a clogged cat so he took it out and put a pipe in its place but no luck still did the same thing. So took it to no 3 mechanic he said it mite be the the coils, computer,egr valve, fuel pump,crank sensor, injectors tested and cleaned so he changed the lot but still no difference and now about 1800 dent in my wallet. so what it do,s now is it drives mint as when you first start it but soon as it gets warm and you put load on it ie going up hills or in 4th gear and you put your foot down it pop in the front then back fires and loses a ton of power. smells hard of un burnt fuel some time if you are driving it and it do's it you can turn the key on and off when you are driving and it will come right for a bit but then comes back any ideas guys??????
