Thanks for choosing FixYa and welcome. This is a hard solution to point out because it could be a power surge from something. A idle control sensor or map sensor can cause it to spike. You may need an idle adjustment. If you have a check engine light on, take it to Autozone and have it scanned. If not, your best bet is having it put on a diagnostic machine instead of throwing money away on parts you don't need.
