Ok so a few weeks back my 2001 rs developed a hesitation at around 2800rpm, at all throttle positions. Figured it was a vacuum leak, and went through my hoses and cleaned the IAC. It didn't make a difference. Monday morning it stalled out while I was warming it up before work. I started it and had to stay on the throttle to keep it going or it would die. Was bogging out anywhere under 3000 rpm unless over 60 or 70% throttle. Tuesday morning it started fine but the idle is stuck at 2000 rpm. ( I unplugged the IAC harness with no difference to idle and unplugged the vacuum line to from it and it made no difference, not sure if this means anything) As for driving, I can cruise at anything under 10% or so throttle or over 70% or so. Anything in between it falls on its face and starts to flood out it seems, the intake will pop occasionally, and you can smell it running rich as hell. Gas mileage is that of a V8 now as well... TPS? Plugged Cats? Sensor? If anyone can point me in the right direction, it' be greatly appreciated!
