Well the other day i was out driving and i got onto it and it did a misfire type jerk when i got around 5k in 2nd. Well i thought spark plugs. A few days later CEL came on and said MAP sensor low. So i look into that and determine that also could be the issue. Well this morning i went out and put new plugs in my car. Decided to go run just to see if it helped, well it did the jerking again around 5k twice. I decided to try 3rd gear and it went smooth all the way through. then i tried a launch 1st, 2nd, and 3rd, went with no problems. WTF?

 

Bump

 

Was it fully warmed up or just the coolant?
