The title says it all but I’ll try to summarize what happened and what I’ve already tried to solve this issue.

A few weeks ago, the cat heat shield metal sheet came off (rust near the screws) and cut the pre-cat O2 sensor wires and damaged the post-cat O2 sensor wires. Before this, the car was running just fine.

I spare you all the details but I ended up replacing both O2 sensors, the spark plugs and the IAT (all original parts).I replaced the IAT because I went to the dealer and they had a P0113 code and suggested to me I replace it.

I’m at a loss. I’ve spent a lot of time on this (and $$) and the car is not going any better. Help please.

 

Problem solved!

Problem was the ECU reset after replacement of the sensors. A mechanic pointed me to the wrong fuse (7.5A labelled "back-up") while the right one is the 20A labelled "ENG".

Car is now working great like it used to.
