K so must check...

- catalytic conv.
- fuel pressure (and filter)

Truthfully it'll be my mechanic buddy who'll be checking that lol.

The problem intially occured this summer around 115000 miles I think. It never stuttered before that. Initially, I purchased some fuel system cleaner (gumout full fuel sys treatment for high mileage cars) for a few fill ups and noticed a slight decrease in the problem. However, the car kept hesitating slightly. So, I took it on the highway with the thought that I would blow some carbon out of the cylinders via stepping on it a few times. The car kept hesitating under hard accel until the service engine light came on and I got worried. I took the car to autozone and had them scan it and the reader came up "cyl #2 misfire". So, I took the car home and removed the #2 plug, cleaned off some minor build up, and the next time I took the car out, the hesitation porblem was practically non-existent. This got me wondering whether the #2 fuel injector was not working right and fouling the plug. Eventually (within a month), the problem returned and I ended up switching from 89 to 93 just to help out a little. It seemed to work slightly. Annnnd basically for the last couple months the car has been in this state. It runs fine, except for when I really wanna get on it. Although, it has one quirk to it...

If i don't lightly (and I mean very lightly) tap the gas pedal right as the motor fires up, it starts out all wonky like. If I don't tap it right as the motor fires, the car usually starts up at around 700 rpm and then "revs" itself to 1500 and slowly goes back down. And I f#cking hate when this happens, especially when the motor is dead cold and its winter in michigan. I know the block aint gonna crack from 1500 rpm, but it just effin bothers me lol.

I know... it's weird...
