Default AP1 sometimes hesitates, HELP?

Guys, sometimes my AP1 hesitates when I am going slow, second or first gear...like around 2500 to 3000revs. It feels like the car is about to stall, loss of power...then kicks in and gets jerky...then calms down. It's like a loss of power....??? I don't think it's bad gas because I try everything...and it happened for 4 months now.

Do you think the plugs could be bad? I have 50,000KM on the car. Also...can I clean the injectors with a cleaner??

THANKS!

Search map whack or just try changing the map sensor. I had similar problem and did the map whack and I've been good since.
