Merry Christmas everyone,
I'm having an idle issue for the second time, and I'm wondering whether it might be caused by a shady gas station. Here's the story:
I live in VA, mom lives in Jersey. I drove up a month ago, filled up at a gas station (93 octane as always) and afterwards noticed a rough idle...RPMs would go up and down, lights occasionally dim for half a second, and car tries to stall (and a few times it did). This was only a problem when stopped and idling--car seemed completely fine while driving. This happened for a few weeks (I had filled the tank in VA since then), adding fuel injector cleaner did not help. The second week my check engine light came on--engine running lean. Took it to a shop and after they cleaned my air intake system and put some sealant in the vacuum hoses everything worked perfectly.
Now I'm back in NJ, filled up at the same gas station, and right away I'm having the same exact idle problem. I never thought it could have anything to do with the gas or this gas station, but it seems like quite a coincidence. Is it possible that this place is doing something shady with their premium gas and that is what is causing my idle problem? If so, any thoughts on what I can do about it? Octane booster? Any advice would be greatly appreciated.
