ok so i had to put pioneer gas in my car to make it to the next good gas station…so i put 10$ in and it was actally enough to get me home…i get home wait a few seconds to shut off the car and the idol starts going all funny…like droping to 200 going back to normal…and so on …but never shutting off the car totally…so i go back out and put in what i usually do Sonoco 91 (35$ worth) car seems to get better so i go home and shut it off…today i get up to check what it does…same problem…so i watch it idol for about 10 minutes then go out to CT and other stuff to drive and see what happens…seems fine …but then starts doing the problem again…so i put some gasline antifreze in it becase im thinking theres water in the gas i hold it at 2000 RPM and it seems to misfire…anyway just tried now and it runs fine again…so what do you guys think it is? bad gas? Trottle position senson ? MAF ? vaccume line…i dont think it could be fuel pump…or sending until or filter…all new last year…
anyways any help would be apericated if its bad gas i hope it goes away soon
