Newbie engine vibration

[Rnakas]

Hi Everyone,
I'm new to the forum selling my 2002 supercharged tacoma 4dr that I had for the last 11years and just picked up a 2008 sport edition v8! I didn't notice this when I test drove the runner but noticed a couple of days later. Around 1400-1600 rpm the engine has a slight vibration in park. Below 1400 and above 1600 you don't feel it.i don't feel it when I drive also I changed and gapped new plugs and have run 2 full tanks of fuel injection cleaner and still no joy? Anyone out there have this same problem, or is it the norm?
Aloha,
Rick from Hawaii

Did you fallow factory specs when replacing the plugs? aka (brand plugs and torque specs)

also try cleaning the MAF sensor as it can be a culprit here.

Yeah, I torquedvthevplugs and checked the gap per the manual, and those were ok, I'm wondering if like you say the maf sensor could be dirty? It doesn't throw an code either. Thanks for the info, I'll try that out!
