05 Altima

[rhaigh08]

My friends aunt has an Altima it consumes oil. They went on a 10 hour road trip to god knows where. On the way back the RPMs at 65 mph jumped from 2k up to 4k. My guesses were Transmission issue, throttle position sensor, or a vacuum leak.They did not feel any slipping or hard upshifting or down shifting. The car was idling at 1k RPMS in park which is normal and was fine up to 65 MPH. When they were 1 hour away the car returned to normal at 65 MPH it was running at 2k RPMS. Vacuum Leak is still a possibility. So is the tranny I dont know much about these cars but if anybody has an idea drop me a line. Thanks in Advance.

start out by getting a hold of an obd II scanner i guess

<shrugs>

how is the condition of the engine and trans oil now? maybe they need to be changed?

There are no engine codes stored. I heard there was a recall on the engine though I will have to get the engine size cause I believe the 2.5 was the recalled one. She claims the trans fluid has been replced

So that can make the engine race? Since then the engine has not repeated this. It has stopped racing at high speeds. Last I heard.

i'd say take it to the dealer, my car had high idle for a while, then for a while normal, then all of a sudden could not go past 40 one morning. Trust me from my experience GO TO THE DEALER, its the engine/cat/pcm/power valve-reflashing take care of that beside the consumtion. Again take it to the dealer first, get documentation. All my problems went away with a reflash(and a $3000 rebuild nissan didn't want to pay for, i still dont have a cat-source of oil problem that ecm started!)
