so i have a Ka24de-T and i just recently got it Ram tuned to my 20g turbo kit. after tune it ran perfect for a month turbo spooling fine afr read perfect everything was TITS! so i problem happened out of no where one day after talking to a buddy when i was about to leave i started the car and noticed the rpm was lower than normal by 500rpm and checked the afr it was reading 9.5-9.8 running rich as fuuuu! since then which was a week and a half ago everytime i start the car it runs super rich and in 2 days driving to school and work i wasted 60 bucks in gas...

so i decided to check my MAF by starting the car and unplugging it to see if any change. so no change occurred so i decided to buy a new MAF. i switched it with another and same thing the engine still ran rich.

then i did a visual check on my FMIC and couplers but couldnt see anything. really didnt do a hard check since MAF isnt being read.

i also replaced spark plugs thinking maybe im misfiring but no change. i still have yet to change wires to see if those are the problem but i highly doubt it. idk if i have some sort of vacuum leak but car ran perfeclty fine but out of no where i turn it on and ran rich. my exhaust has dark smoke now but its oil and unburnt feul.

so im out of ideas and my last idea is checking wiring... anybody help please im spending tons of money on gas driving locally since this is my daily
