Hey guys I posted a couple of days ago that I got my 15k service I thought I was feeling some hesitation when I was trying to accelerate but I couldn't really test it out until today when I got some open road but it turns out that as soon as I am stepping on the gas to pass a car it hesitates and then takes longer than usual to get up there. Anybody have this issue or recommend anything before I got rip Nissan a new a** hole tomorrow? I'm livid to say the least after doing routine maintenance that cost $330 and no my car runs like ****. Thanks in advance.

 

What did they do on the 15K service? Did they disconnect the battery so the ECM has to relearn your driving habits? Good luck.

 

Maybe check the intake and see if the left it open after the MAF somewhere.

 

So why are you "hesitating" on taking it back to them???...See what I did there?

 

They probably did but this was on Monday they did brake flush fuel injector cleaning and some other things that shouldn't effect it. I haven't had time I work 0530-6 and they're closed by the time I get out. Real clever though.

 

I would put money a loose vacuum line or the fuel injector flush, which you didn't need, unless you run really cheap gas and have over 100k miles on the car. I've never had this service on my 5th or 7th gen cars and the cars run just as good now MPG and throttle response wise as when I got them.

 

I never put cheap gas I only put shell v-power and I usually run a bottle of Lucus fuel treatment once a month but they said it was recommended and I plan I keeping it for a while so I figured why not. I probably should have asked you guys on here first but too late now. Anyway I just got back they said it was throwing codes even though it wasn't giving me a check engine light? They reset some stuff said it was running rich due to the injector cleaning and to monitor it this weekend. On the drive home I got on it and it feels like a brand new car and the quickness that it's capable of is back so whatever they did worked thankfully. Thanks for the help everyone!

 

^^^Um, that info the dealer just told you is a line of BULL! Running rich because of an injector clean? Thats the kind of BS that would **** me the F off!

I bet it was something silly like what I asked you to check, like a leak after the MAF from them not tightening the intake tract. Something like that.

 

Great I knew they were being shady thanks for the info if I would have seen it prior to going I would have checked I quickly looked last night but not thoroughly. I'm just glad she's back to normal.

 

Besides, your whole MAP on your ECU is ran from your OBDII system and 02 sensors front and back among the MAF to determine the fuel ratio and how much fuel is added to the cylinder that will prevent detonation. So that said, you can put 87 octane in your car and it shouldn't hesitate or knock.
