It's using heaps of fuel and just feels really deprived. Happened shortly after I gave it a bit then back fired. Have checked all hoses and replaced a cooler hose because it had a split in it but that didn't fix nothing, also tried by-passing the boost solenoid but also nothing. Coils and plugs have been checked so that's out of the question. Have put a hole in the cat about the size of a 50 cent piece so the cats not blocked. Have changed the fuel filter as well. This has happened shortly after a new tune, oil pump gears and vavle springs were done due to a misfire. It was running fine up until this problem Car has 4 inch exhaust Turbo smart 1200 fpr Twin walbro 460s with surge tank 1000cc injectors Pw stage 1 cooler Gt3582r Lots of others I can't think of What could the problem be before I travel 220 ks to my tuner? Thanks for any help Link to comment Share on other sites More sharing options...
