Need some help..Rough Idle
Hey guys when my car sits at idle the car seems to rev it self up a bit then drop alittle below idle. The car calls for 91-93 oct based on my mods. The other day my dad put about a 1/4 of a tank of 87 oct in the car by mistake...Not sure if that would make a difference seeing as the rest of the gas in the car is 93 oct. My second thought was an bad 02 sensor, and last thing I thought of was a bad fuel injector. Whats going on here???? Thanks
