My car is making a slight popping noise at idle sometimes it does it sometimes it does not. Its usuualy when I start it after is warmed up. Any ideas? Plugs, wires maybe tps?

I would like to know if anyone could tell me the measurements on the *DM radiator? Trying to see basically if this is a *DM radiator or not? Radiator came with no info and really not sure what to make of it. Might be a tep radiator just not sure. Thanks for any info relating to this.
