07 Wrx Tr
Driving conditions where slightly misty, mostly from other other cars. I noticed the 1st and 2nd gear stutter after about 30 miles of very heavy rain.
Today driving down the highway my car was running strong and smooth, but then it just died. I pulled into a gas station and fired it up just fine. Filled it up and was on my way. I noticed as soon as i got back on the road it had a little stutter to it.
It only stutters when I go from very little throttle to 40% or better, like in a passing situation or downshifting. Its kinda jerky but only for a second or two then its smooth. If i ease the throttle in it doesn't skip a beat. I haven't noticed a loss of any vacuum or Psi. Maybe a little power loss but maybe I'm paranoid. It still pulls pretty hard.
If I am in 1st or 2nd and I try to coast with no throttle its very jerky unlike before.
Same symptoms but now I have a CEL, P0172
