I have a 2005 G35 Sedan. only thing not stock is K&N AF and LED bulbs. almost 108k miles. Always pumped shell 93 and this is the first problem I have faced with my car

I went on vacation and left my car at the airport for 5 days. When i got back i immediately noticed the car pulling a little harder when accelerating and when i was braking.

Now my symptoms are when i am in drive and off the gas engine creeps up to 1.6k rpm. It'll even shift to second gear and creep up again to 1.6k.

One fellow said i'd have to replace my throttle body, a friend said idler valve may be stuck, and another friend said the TB may just need a cleaning.

I've had 3 different opinions and wanted to see if anyone on the forums had a similar problem/solution or can confirm if any of these are the solution before i have any work done.

TIA,
JEAT

When i am at a complete stop and in drive and on the brake car idles normally @ ~800rpm
