It was recommended that I do a fuel induction cleaning on my 2000 Avalon (112,000 miles). I did it and when I drove my car for a few times I noticed a delay in acceleration for a split second after hitting the gas pedal. That ended up going away and later on in the day after starting up my car again, it felt like the engine was going to stall. I hit the gas a little and drove the car and then the check engine light came up.
So, I took it in to another mechanic and they said something about Lean Bank 1 and the recommended fix was to replace the mass air flow sensor.
My question is did Mechanic 1 who did the fuel induction service screw up my car? I assume yes since the check engine light came on the same day but want to give him the benefit of the doubt before writing a bad review.
