Hello! I know this has been posted before, but I haven’t seen anyone post a resolution. My apologies if I’ve overlooked it.
I have a 2009 LE Auto with 37k miles on it. About two weeks ago when stopped at a stop sign, the car started to vibrate and it felt like it was about to shudder and die. It didn’t and I made it home no problem. Now I’m noticing that it will start to vibrate when in drive while I’m stopped and also when I back up at slow speed. The RPMs will drop to about 600 when this happens and then it goes back up to 800-1000. I always have my AC on. I notice that when I turn my lights on it won’t drop to 600 and it doesn’t vibrate. This is a new problem. The RPM has always dropped to 800 and maybe a bit below since I’ve bought it in April, 2008.
I have gotten oil changes regularly but haven’t changed the spark plugs ever. It’s 12.5 years old but had low miles. I ordered some Royal Purple Max Fuel Cleaner to try thinking that it maybe have something to do with the fuel. I got Costco gas the last two fill ups (coincidentally when this started). Also, there were long periods were the car wasn’t driven regularly (months at a time) due to extensive work travel. I have been driving it daily since April of this year.
I’ve read so many different suggestions on here on other posts and I cannot see a resolution about what was going on. I read it could be head gasket, O2 sensor, mass airflow sensor, clean/replace throttle body and motor mounts. Does anyone know what’s going on or had any luck with solving this problem? The vibration isn’t the end of the world, but if it’s the beginning of something big, I’d like to address it now.
Thanks in advance!
