Car hesitating
My car is having some issues hesitating from time to time. When I was at high elevation, filled my tank at a random gas station and tried to accelerate quickly it got even worse.
Prior to that I was using shell 91. Any ideas of what could be causing it? One time it threw a code, I believe it was P0300 |

I think P0300 is random misfire. I believe changing different brands/level of gas might make the car run funny without a fuse pull.

Probably just the gas, but check your plug wires and plugs to be sure something is not going on in that area.

at high elevation there is less air for it to suck in, and as a result it won't be as responsive or powerful.

Actually the atmosphere at high elevation is identical to that at sea level.....same amount of air is available for sucking, but the car can't suck in as much as sea level due to reduced air pressure.

I find this to be incorrect. If that were the case, people would not need oxygen bottles to climb Mount Everest. There is a definite reduction in the amount of oxygen to burn the higher in elevation you go. A car will pull the same amount of "air" at altitude, but the amount of oxygen available to burn is less. It's a 3-5% reduction In Power per 1000 feet of elevation.

There isn't any plug wires to check. They're coils sending your spark. It's gas most likely. I went to a ported throttle body and mine improved some.
And as everyone else has stated, elevation will play a roll in it too.

Yup, it's Boyle's law, and you just can't up and change that...
