Explain more detail

@alltsab ok, so I have my 2005 tacoma engine replace 2 years ago, but the after the new motor replacement. This new motor kind shaking or vibration when you stop at a stop. And the idle kind move up and down a little but only below 1000k rpm. I used brake cleaner to check for air leak but nothing. Therefore I just want to see if you experienced this before. Thank you

@kenjie316yeung7 1000k rpm still shaking? Any engine light?

@alltsab no engine light and I haven't try idle at 1000k rpm . I have replace spark plug already.

@kenjie316yeung7 check your compression to see all cylinder are equal compression.
