hi gurus,what do you think is the problem that I am about to face? last friday I let my engine running for 9 hours under the SUN! ang init kase sa school walang covered parking...during that entire 9 hours idle lang talaga sya(800RPM - 900RPM when compressor engage) hindi ko na ni re-rev yung engine..aircon is on saka yung mga monitors and head unit bukas so extra load sa alternator......2012 suzuki apv pala tong sasakyan na to...thanks guys!
