Hey guys just swapped my 09 Lancer for a R34 GT-T and I'm loving it! Recent problems that I have had in last 2 days, Rough Idle. Rough idle is on start up, when cold and when the A/C is first turned on. It will stall every now and then from these things but its not chugging it just lowers the revs right down and just stops and then starts up just fine again.. Misfiring? The car only does this down the low (1500rpm-2000rpm) and high (4500rpms-7000rpm) revs of the car, its just one or two misfires down low but when you hit full boost at 4000rpm the misfiring goes crazy at about 5500rpm and does not stop till the revs go back down.. Fuel Economy! So I'm driving not too fast doing the speed limits not excessively boosting or anything have it in 5th gear at 60kmp/h and I'm just reaching 300kms from a full tank! The guy I bought it off said he gets 450-500kms from a tank. When changing down gears the amount of fuel that you can hear being burnt is ridiculous! I love the sound but I rather drive the car for longer!! So mods that the car has: GT30/40 Turbo Adaptronic ECU (tuned) 3" Turbo Back Exhaust Air Intake Intercooler 12Psi 240rwkw Stock Injectors tho etc.. I've done some searching and there was one really good post on here but the links no longer work because it is too old, so if anyone could either direct me to a link or give me some info that would be great!! I have a feeling it's spark plugs or tune? Hope it's something small and not expensive $$$ Thanks everyone!
