We just got a good deal on a nice 41K mile Infiniti I30.
But two things are wrong. After a few minutes, when driving at a low but constant speed in overdrive, the engine speed will decrease and increase about every couple of seconds. You feel and see this pulse on the tach. Running at freeway speeds eliminates these pulses as does disabling overdrive at the lower speeds.
It may be related to the AMB button that is suspose to display Ambient temperature, except it ALWAYS displays 117 degrees. Also I can't find the sensor for this "in front of the radiator???"

Any advice?

Bumping this. Same problem (below) with engine/transmission. Infiniti dealer wanted to replace the transmisssion. We said no.
Other problem, the AMB sensor was missing and the wires wrapped around the wiring harness. That's fixed now.

 

Ummmm... Why did you say no to a new transmission? You should still be under warrantee. Ill take a free transmission!

 

Sounds like the torque converter might be locking and unlocking for no good reason? Not really sure. Why don't you want to let them replace the transmission? It's under a 5 year 60000 mile powertrain warranty so they should have to replace it with an OEM Nissan unit. Should make it good as new.

 

Hell, Ive even got a 7 year, 100k warrantee and would think you do too. If I got my tranny replaced, I would replace the ATF with synthetic and do the VB upgrade.

 

Take the free tranny. Im doing that this month on my 99 max. Ive got 4 weeks left on the warranty and 5k miles. Once the new tranny goes in, hello Synthetic, Tranny cooler, and VB mod.
