So the person I bought the 2001 infiniti i30t from had previously been using regular 87 octane gas in the car (despite the fact that it requires 91 octane or above). He said that the car back in the summer (july) had a misfire in cylinder #6 and I automatically attributed that to the fact that he was using regular which made the engine retard rather than run normally on rhythm, he said the problem just went away one day and since hasnt come back. I recieved the car one full tank of 87 octane gas and last night it finsihed and i filled it up with 91 octane premium gas and drove 41 miles on it today(when i filled it up, I put roughly 15.8 gallons of premium in an 18.5 gallon tank, meaning there probably was some residual 87 gas left.
Point is, 20 minutes ago, I started the engine and it was rough and slightly jerky on idle, the check engine light, traction control and slip lights all came on. It felt the same way you would feel if you had terrible rotors and you were breaking, or as though you were driving on a really bumpy road.
Could it be that my engine had adjusted to the regular gas being used by the previous owner and by adjusting im implying the engine reatrds and gets used to it if thats even possible.
ps. I just turned it on and its back to normal but im not sure if its going to stay that way, and the Check engine light came on and i havnt had the chance to check the code.
Does anyone know whats going on
the engine is a 3.0L V6 227hp VQ30DE
Thanks!
