Weird Pinging/knocking unde slight acceleration
Hey all, i've noticed that whenever I either go from a complete stop or let off the gas and coast for a second or 2 then give it gas I get a weird pinging/knocking noise for 1-3 seconds. I cant figure out what this could be but it seems to be worse whenever its really hot outside or right after start up and the car is still a bit cold. The odd thing is that it only does it under those 2 conditions, whenever I give it a lot of gas it doesn't do it so I'm kind of stumped.

I always use 91. I thought it might be the plugs but I figured it would do it under hard acceleration as well? I bought it with 134k and have not changed the plugs so who know the last time they were changed. Air filter is new. When you say clean the throttle do you mean the throttle body??
