2011 chevy cruze eco 135,000 milesSo I took my car to the shop and got a smoke test for the p0171 code and +22 LTFT, They found the PCV leaking. My wife went and told them to replace it ( I was sleeping SMH) well $270 later. (it makes me sick over a $48 part I could of did in my sleep). I get the car back. I drive it home around 45 Degrees out, LTFT is staying around 0 to +7. I start it after work, Temps in the 20s it idles like crap, and almost stalls twice. LTFT was at +32 and a pending p0171 code. Drove it home, LTFT was staying around +7, idle after warm up around +6. Got home, tried to see if there was another air leak, I cant find one, after messing around it set of a p1011 code, Im not sure if it was from me. It set off that code once before, but when I reset it it never came back just the p0171. Does anyone know correct MAF readings on the cruze?And any ideas on my Rough idle only on a Very cold temp start, and high LTFT still after pcv was changed?PS Manisfold does have the orange check valve present.
