Maybe you left an air hose disconnected or lose? Or any other connector?
I guess you already check the coils if they are well connected. If one is failing, you can also unplug one at the time to see if you find the one bad.

Assuming the battery was disconnected for the install, did you go through the re-teach procedure for the computter?

It's in the owner's manual, if you don't have it, Bucko has posted a link to an online manual in a couple of threads.

Here is what my 2005 owners manual states about this:

Because your vehicle’s engine is also electronically controlled by a
computer, some control conditions are maintained by power from the
battery. When the battery is disconnected or a new battery is installed,
the engine must relearn its idle and fuel trim strategy for optimum
driveability and performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park) (automatic transmission) or the neutral
position (manual transmission), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
