Car doesnt accelerate as fast anymore

NISMO IX · 04-09-2018, 06:24 PM

I don't know why this is bringing back memories but, I had an 06 Sentra Spec-V that threw a code at 20k miles and went into limp mode. Dealer said it was the throttle position sensor or something along those lines. They replaced under warranty and all was good until 600-700 miles later when it happened again. My remedy, I went to the store and bought some purple power, and used that with a good power wash under the hood in the engine bay. Reset the battery and never had another "Service Engine Soon" light again, and trade it in with 93k miles on it.

Not recommending you do this, it is what worked for me on a different Nissan model.

You can buy a reader off Amazon for pretty cheap. Get the codes and post them here, I am pretty sure someone can help you.

clean your mass airflow sensors and your throttle bodies...there is a tutorial on youtube, it happened to me and my car flies now better than I can think off, time-consuming but easy to do

The OP doesn't sound like he knows much about working on a car. Probably telling him to clean MAFS is a bad idea. Best thing for you to do OP is to call a mobile mechanic and make sure he's got good reviews on Google at least. Make sure to call him while the check engine light is on not after you or anyone else has reset the ecu. Ask him for the specific codes after he diagnoses your car .We cannot stress that enough.
