I have a 2005 Mt 350z and I went to start my car today and it took a few times and I had to give her gas to get her going. All the lights came on and it wouldn't Rev past 1000rpms. No power what so ever. Recently cleaned my throttle body (didn't touch the butterfly) and did cam positioning see sensors. I turned the car off then on and gave her gas again and the slip and traction control light turned off and just the check engine light remained but the car had full power. Any suggestions? Asking because I don't want to drive her and mess something up.

 

I had the same problem. turned out to bad bad TB and TPS sensor

 

Yeah it was the tps sensor. I replaced the throttle body unit. Do you happen to have th throttle relearn for a 2005 manual Trans 350z by any chance. Now it revs high around 1500 rpms and when I give it gas it keeps accelerating even after I release to around 3k

Bamdon, what did you use to clean?

 

Throttle body cleaning seems to hurt these cars more than it ever helps

 

was your car not passing a certain rpm and also your slip and tcs light turned on and wouldn’t go up to speed? Lmk please TIA
