Got my car tuned by jesse and it was running great then the dtc code po172&po175 popped up, got a new maf sensor new 02 sensors and still running rich.So i bought a new coolant sensor and took out the old one and try to put the new one in but the new senor does not fit. I put the old sensor back in and now i got po135 code and i can't clear it what should i do.

Re: Did i mess my car up? Need your guys info!
Sounds like the right side (Passenger) O2 is bad. The other codes might be from your intake coming loose somewhere, although that usually results in lean codes. Maybe Jesse put the wrong MAF curve in there.
Edit: p0135 is an O2 code. P0315 is crank sensor position learn code. The sensor might be going bad.
Then I would look over where I was to see what I bumped or knocked off.
Can't imagine that a leaking intake would cause a rich code though. Usually it causes a lean code. Maybe check for an exhaust leak too. But for me if I changed out a sensor and get a new code I am going to look over what I did to make sure I didn't knock off something else.
Is your ECM a new one? Usually PO315 is associated with installing a new ECM. It happened with my car
and The only way I could clear it was by going to the dealer and have them perform a Crankshaft Variation
Relearn. Unfortunately you need Tech 2 software to do this. Also the sensor is located beneath the supercharger.
You can drive the car with this condition and it won't harm it according to my dealer. I just didn't push the car
very hard under that condition.
