Hello everyone! I'm having a problem with my 2001 v6 automatic. I was at walmart and grabbed a bottle of heet (red) because every once in a while my car has a little trouble staying running. I put it in the gas tank immediately which was almost full and let it run for a bit before leaving the parking lot to head to my next stop in my list of errands. It ran fine I got to my next stop, get what i need and leave. As i was pulling out of the parking lot it seemed a little sluggish but okay. then I come to a stop at a light and it starts to idle rough like my old saturn did before I cleaned out my EGR valve and my check engine light flashes at me. I pull off, shut the engine off and it starts right up but up until I hit about 2500 rpm it idles rough. The other thing is that now any time my traction control is active I have a strange whining coming from the passenger side of the dashboard. The traction control issue is something I am almost positive was caused by the traction control being on almost the whole time trying to make it home in the storm that hit my area on Tuesday but the rough idle I can only assume was caused by the addition of heet to my gas tank. Any ideas on how to fix the idle problem would be appreciated. Thanks!
