Dropping rpm shake

Hello when I rev my engine up in park it revs up fine but when it’s coming down to idle I get a shake. Could that be spark plugs? Truck has 200k miles idk if plugs have ever been changed? Or could that be another issue. (Currently looking for a solution for my steering wheel shake I have another post on that )

 

For an idle shake, may be a good time to check on those spark plugs, check for residue, if you really don't know when they were replaced last, then replace them. They're supposed to be changed out every 100k miles. If that doesn't settle the issue, then it could be gas related, if it's been sitting a while, or an Idle Air Control issue IACV, but first thing is first check on the sparks. If there is any type of residue besides oil, you may readjust your search from there.

For steering wheel shake, there is a TSB out for the power steering issues, it encompasses most Tundras and Sequoias, all the way to '07, I got a notice on this,

 

Thanks for the reply I will try spark plugs. My tundra is a 2016 would that power steering still be the issue for the shake?

 

I can't find the TSB, but drop your vin on the NHTSA site, and it should tell you. If its in there print it out and take it to your local dealer, or call them and make an appointment.

Awesome thanks they fix it even if you aren’t the original owner or regardless of miles? Free?

 

that would be my assumption. I got the window regulator replaced about 5 years ago at 170k, and my truck is an '07

 

Nice
