I just bought DDD’s 01 2zzge Spyder. It had been sitting for 2 years, so I drained the gas, replaced a bad coil pack, put in some new plugs, and now it’s running pretty good, but not great. It cuts out when you step on it, especially in a high gear. Feels like it’s not getting enough fuel. I’m wondering if the injectors might be dirty, how to check for that, or what else I should be looking at. Any ideas or suggestions would be appreciated.

So I drove it about 20 miles last night, and the check engine light finally came on. p0300 and p0304 came up on the scanner, while p0303 came up a few days earlier. Seems like just random misfires, causing bucking and surging. To me, this would point to something like low fuel pressure or even a vacuum leak. Is there any way to monitor fuel pressure using techstream? Is it at all likely that I have more bad coils?
