my pontiac recently started to hesitate and shake everytime i would step on the gas. it was after i had poured in gas. i stopped somewhere for awhile and when i turned on the car it was just shaking like if the spark plugs and wires were no good but i had just changed them about three months back.also the check engine light was also blinking.i took it to get the codes read again and it told me cylinder 3 misfire. i took it to a mechanic and left it there for about an hour and he called me back and told me that it was done and that the car was fine. He had told me that all he did was move some wires around to connect them again and he put octane booster in it. he just told me the next time i put gas to put a bottle of it also. so i did, and sure enough the car started to do it again but this time while i would try to accelerate. everytime i would get to about 50 55 mph it would hesitate the rpm would go up and down the light would flash again then the car would go again. it does this everytime i go that speed. also every time i start the car
