Just recently I noticed when I slow down in 2nd, 3rd,4th, or 5th gear inbetween 1k-2k rpm that my engine studders (as in shakes back and forth) until I get past 2k rpm, or if I mash the gas pedal between those rpm I noticed my engined goes really slow until it gets past about 2100k rpm and it launches fast (feels like a mini turbo). It never did this before and is getting on my nerves because I have to go over a lot of speed bumps when I go to class and I dont want to go to first gear everytime I am driving around 15mph. So if you have any idea's why this is happening please post. (also it started around when I put some 91 octane gas in my car by mistake, I dont think this matters since I used all that gas and refilled it with 87 and its still doing it.)

Try resetting the ECU by disconecting the battery for 5 mins.

This could be injectors need cleaning, a bad oxygen sensor, bad spark plugs.

...even bad gas; happened to my moms car...rough idle, funny acting--next tank...smooth.

Dont go to econo gas stations.

Yeah I thought it was the gas too but I went through a tank of 91 octane at chevron, then after that I went back to 87 octane with exxon which both are two pretty good gasoline places (I get 90% of my gas from exxon) and I do avoid the "econo gas stations", but still it jerks.
