The other day i was driving on the highway probably 75ish mph.... i went to pass some one so i downshifted from 6th to 5th for just a little bit extra power. When i got it into gear and pressed the gas the car did nothing. No rpm difference though. They didn’t rise or drop, but the car did absolutely nothing. So i shifted back into 6th and hit the gas and it did nothing. Same as when i had down shifted, no change (rise or fall in rpms) but also didn’t go. I put it in neutral for a few seconds, put it back in 6th and it went again. I feel like i can’t really get on it hard anymore. Then a few days later i was in 3rd and went to gas it and i think it hit like maybe 4500/5k rpms and then it acted like it was red lining..... i have no clue wtf is going on. Any advice or point me to another thread please and thank you!!!!

get it scanned, sounds like limp mode due to camshaft position sensors. (Doesn't always throw codes.)

Are you throwing any codes?

I am experiencing the same symptoms as described by the OP. It typically happens after an aggressive/missed downshift on the highway to try and pass someone. The only way to resolve the mode that I've found - and get back to normal engine response - is to cruise along and maintain speed for 10s or so. After that, things seem to be OK. Also, the SLIP light is lit when I try to accelerate when it's mis-behaving (though the road isn't slippery, and I'm traveling over 55mph, typically).

I have 125k miles on mine, and I have no reason to suspect that the cam sensors had been replaced before. Thanks for the tips!

Okay so I’ve since got a code.... p1283. Nissan just replaced my O2 sensor bank 2 on Monday, drove it yesterday and the service engine light comes on so i run it to advanced to get the code checked since i was right next to one and it’s the same code..... also, this did not occur after a missed downshift.... went from 6-5th with no issues aside from what was mentioned. So now Nissan is going to have to look at it again, just dropped it off about 30 min ago.....

Thanks for the information on the issue i posted about guy..... I’ll be sure to get that pertinent information to Nissan!

Update on the issue..... they claim they didn’t do anything but i took it back to Nissan last night, tech takes it for a test drive today and claims the light goes off. Has it on the computer doing diagnostics and running it and tells me that all of the sudden it starts spewing coolant and steam starts coming from under my hood..... says the fans won’t work now. The car again is an 04 and just turned 72k miles..... the thing has never had an issue until recently.... no clue what to think at this point.

Update...... they had me replace both upstream and downstream o2 sensors and said the cat was bad so i replaced those with high flow cats..... so far no CEL so I’m hoping it’s fixed.....





Lol “noob”.... **** off guy..... the only people who use the word noob are acne infested queerbaits who sit in their parents basement and play video games..... have a splendid day....

You may want to be a bit more careful when choosing your words. That is a great way to get yourself blacklisted from help by others, or even better, banned.

Nope, have my own house, dont play video games, and can do my own troubleshooting. You are wrong on so many levels noobster
