today i was at walmart and i put the car in park. it all of a sudden turns off but all the lights and air con was still on. i figure maybe i jus turned it off *been all all day and tired because girlfriend went inside walmart to buy sumthing*. then while on the way home at a red light the rpm drops kinda like its was about to die out but went back to normal. everything was all fine on the way home.
does anyone know whats wrong? any suggestions? i was thinking its the spark plugs. anyone? thanks in advance.

 

Maybe the MAF sensor is dirty. Have you ever cleaned it?

 

wheres the MFA sensor? how do you clean it? sorry noobie to GS300s

 

Just a guess but maybe the alternator.

 

i have any ideas for you but good thing it didn't happen while you were going 70 mph on the freeway.. good luck

 

i know huh. i drove the car this morning and it ran fine. i figured out what MAF was. Mass Air Flow Sensor and did some research on why u need to clean it. ima go ahead and clean it out today when i buy the cleaner and hopefully this prob wont happen again.

 

My landcruiser did this about a year back. I would have them check your battery. Sounds like your battery is not charging. It can happen.

 

ill go check on that

 

yeah, i had both scenarios. battery was not charging properly and the maf was dirty. replaced the battery and cleaned the maf and everything has been great since.

 

havent cleaned the maf or checked the battery yet but drove car today and it ran fine but will check/fix problem.
