p0134, p0171 Idles too high, running hotter than usual
Car is running a little hotter than it used to. I am getting a P0134, bank 1 sensor 1 no activity, and a code p0171 bank one running lean. Can all this be causing the engine to overheat some due to stress from the lean condition? I had a P1294 which was target idle not reached. I cleared these codes and it came up with the P0134 again and P0171.
I have checked for leaks. Cleaned the iac, map sensor, and the pcv valve. Any help would be appreciated. The car when cranked goes up to 2200 rpm then goes down to around 1250. Occasionally on a cold start it will go down to around 800.
The car also when driving slow and you let off the gas to like go over a speed bump, it feels like you still got your foot on the gas a little and it finally idles down. Could this be a faulty iac valve causing that?
