hi well this is my first post i hope its in the right section. anyways i just came from a vw r32 and bought my 07 350z 2 days ago, by the time i got home it had a check engine light. the code was for cylinder 5 misfire, noticed a high idle which it stay around 1000rpm and figured this was because of a lean condition causing the ecu to make it run rich? sometimes i start the car and the CEL is off and its back down to idling around 700? i pulled the intake today and im just so confused, maybe someone could help me with ideas.

the car is an 07 with the vq35hr and 56k miles
also one port is really clean?

 

damn kinda makes me nervous. im buying an 07 from a guy i know. should get it next month. 51k miles and it has never been modded. with no warranty i cant afford that

 

how much are you suppose to be picking it up for? jw. but anyways it turned out to be the spark plug wasnt tight enough so it was blowing out of the sparkplug hole

 

well its got 1500 of audio into so a lil more than kbb value. and 19800

and good thats a relief
