Customer Question
I have a 2009...

I have a 2009 Nissan Sentra that runs very rough and wants to die in reverse. No power either

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

You have to pump the throttle to keep it running but does not want to back up

Mechanic's Assistant: Are you fixing your Sentra yourself? What have you tried so far?

Yes, replace the Mass Air flow sensor and ran a can of catalitic converter cleaner thru the tank of gas

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Sometimes after taking it out of reverse it takes several minutes before the car will idle

Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!

you may need to do a idle air relearn, here is a video on how , if it dosent take you may need to take it to dealer for proper relearn, I have had a lot of trouble with those over the years even with factory software I have had to do the relearn sometimes up to 5 times to get it to take
