Good day, please my vehicle listed above use to trip off whenever I want to make u-turn or reverse in a tight road. My mechanic said I should change fuel pump and timing belt which he did but the problem persists. What can be the problem and solutions? I need your urgent response.

When I did the scanning, I got code P0136 oxygen sensor Bank 1 sensor 2 malfunctioning.

I need your urgent response on the issues of tripping off of the car whenever I make u-turn.

Hi:

I'm not sure why he questioned a timing belt or the pump. I can't see how they would fail in reverse or u-turns only. As far as the issue, the code you have is specific to an oxygen sensor. Again, I don't see a correlation between the two. However, anything is possible.

Is it possible for you to let me know what the fuel trims are when this happens? Basically, there are short term and long term trims. I need the short term fuel trims to see how the computer is adjusting for the oxygen sensor.

Next, I realize the fuel pump was replaced. However, has fuel pressure been confirmed in spec?

Let me know. Also, let me know if the engine just stalls like you turn the key off or if it slowly dies.

I will watch for your reply

Joe
