Hi,

I have a 2008 Vios AT G which has LPG kit. I am not using the LPG kit for more than a year a now. During heavy traffic this morning, bumababa to 500rpm idling and parang mamamatay yung makina. then after a while temperature gauge lit up. Turned off the AC after a while temp gauge went off pero I still feel na medyo affected acceleration due to low idling. Went to a gas station and had my radiator checked pero full naman sya. Had oil and sparkplug changed around 3 weeks ago lang.
Ano kaya possible problems and ano pwede ko pacheck? Thank you.
