So to make a long story short I bought a 04 6mt with 92k Miles. Single owner and in great condition! As soon as I got off the lot and on the street SES light comes on. Had my brother in law check the code at Auto zone. It was the TPS. Forgot the code that came up but it said TPS. So took it back to the dealer and the took it to Nissan and fixed it at their expense. So got it back 2 days later and wow the car pulled harder and felt real powerful! So 3 miles later SES comes on again... Pull the code and this time its p0507 Which is the Idle Control System and says Idle Control System RPM Higher Than Expected. I cant find any intake leaks at all. But I havent taken it all apart yet. I had my brother in law go ahead and clear the code and I also did the idle relearn thing so the SES light finally went away after the 3rd time. The car isnt feeling as powerful as after they fixed the TPS. Any help??
Thanks alot!!

idk about that g35 but in mine "TPS" is for the tire pressure sensors. that being said.....unless your tires were flat it should've made and change in how the car pulls. when i bought mine the TPS light was on and all they did at Infiniti was change the batteries out but thats it. The other code is what is affecting your performance. i'd take it to a dealer and have them quote you on fixing it

 

Throttle positioning Sensor. Sorry i came from 3si forums and TPS has always been throttle positioning sensor... Haha prob solved tho. It was a clogged cat.
