No check engine light? Look for any vacuum lines that may be off and check the IAC valve/motor it may have stuck wide open when the amps went up. It is very easy to clean with carb cleaner the carbon build up has a tendency to cause this valve to stick. I would check these items first. Let me know how that works out.
Good Luck.
