Customer Question

I have a 2007 Nissan Sentra, 2.0. I repaced the spark plugs. Now the rpms go up and down. Do you have any idea what could be the problem?
JA: How many miles are on the car? When was the last time the plugs were changed?
Customer: 104,000 miles. Just bought the car in June 2017. Don't know last time changed. They were very wore out.
JA: Are you fixing your Sentra yourself? What have you tried so far?
Customer: yes. just changed spark plugs is all. RPMs didn't go up and down till changed spark plugs.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I wiped the throttle body out with a rag a little while changing plugs is all.

Was the battery disconnected while you did the work?

Or the throttle body?
