Engine Hesitation

I hope that someone can help me. My 98 Grand Am GT 2.4L 5 speed, was running with no problems. I decided to replace the spark plugs with bosche +2 and I started having hesitation problems. I replaced the spark plugs with bosche platinums and it seemed to fix the problem for about a month and now it is back. It has a hesitation only at lower rpm's. I can also feel a hesitation at idle and can be heard.

Thanks in advance

I have had problems with Bosch in the past with my Mazda. I ended up going with the OEM plugs for the car. Yours are AC 41-910. Gap is .060 inch. Check your air filter too.

I was wondering if the Bosch plugs are the problem. I will have to try replacing them with OEM to see if that is the problem.

Today my 98 grand am had a misfire in cylinder #2. This is the second time that this has happened. I deleted the code. Can anyone tell me what that means.
