Default car feels jerky after plug change

iv just done the spark plugs on my 2003 wrx ppp and the car feels quite jerky when driving, doesnt sound like its missing in the engine but its spluttering on when im driving it, not when idleing. iv had the battery off, so could it of reset my ecu?

last time i had the battery off it was a bit dodgey for a few days!

help please

thanks

I'm thinking gaps too, did you gap them and if so what size gap? Generally .65mm is good.

0.8's a little big. As above .65 works better. If you have done 0.08? Thats to small

.8 is def to big,iirc the ideal gap for a newage car is .7 and they come from the factory set at .7 so need to set,best to check em anyway tho.
