Mercury xri spark plug question

[Fordracing17]

Hey guys I have a 1994 mercury xri currently running bu8h plugs. My question is there another plug that I could run that could help with some fouling. I have tps currently set to .210 but if I idle around alot it seems to load up fuel and I have to rev engine in idle to clear it up then it's fine. I realize I might have another problem going on but I was just curious about a different plug that might help

Thank you

different plugs won't do much...

ecu number?

824003 A1, 2 or 3?

till ya figure it out keep it trimmed a little positive at idle if your not doin' it now... oem manual?

tried tpi at .250?... should have an "idle speed controller" on it.. roughly 3" x 4" black box with a red/white, white/ black going to a switch box... trash it.. reset timing at idle in tha water, in gear ta what ever makes you and tha motor happy... book timing at idle doesn't always work out.

could be a coupla other things also. leaky/bad injector or o-ring etc....

Gee, I have a '93 Merc V6 with carbs. She idles perfectly. One would think a newer, more advanced motor would work as well.

I will remove box is it possible to give me a quick run down on timing as far as starting point and how to adjust we are starting to get out of my knowledge

I do have access to timing light but just curious of tricks from somebody who knows I know it is probably alot to explain in forum but I would really it thanks
