timing belt change. off teeth?
alright so i did my timing belt 2 days ago for my first time ever. i had the crank and cam lined up put the belts and everything back together started it up clicked oddly for a few seconds the idled normal. but whenever i got on it, it was laggy and sounded odd. so i took it all apart today turns off i was off one tooth since maybe i didnt double check. so i realigned it. manually turned the motor over to make sure they were still lined up. checked out put it all back together. still no power if not less then before and i was 100% positive i had it lined up perfect. i can snap pics tomorrow but for some reason i feel like its no longer the problem. the car lags and sounds a little throatier and leaf blower like. everything was fine till this.

Your Timing is off, unless you have a timing light you are not going to be able to adjust this properly. Either go get one or take your car into a shop and have it fixed.

yeah, for EFI systems with cam and crank angle sensors you don't need a timing light, as long as the mechanical timing is bang on, the ECU will take care of the rest...and the 4G94 has no externally timed balance shafts you just need to make sure you used the proper precedure...these are the steps from the manual...hopefully you're not getting piston/valve interference...
TIMING BELT INSTALLATION
1. Align the crankshaft sprocket timing mark with the timing
mark on the front case, and then rotate the crankshaft
sprocket three teeth counterclockwise.
CAUTION
Aligning the timing marks positions the piston to the top
dead center. Then, if the camshaft turns, the valves might
interfere and damage the pistons.
2. Align the camshaft sprocket timing mark with the timing
mark on the cylinder head.
3. Rotate the crankshaft sprocket three teeth
counterclockwise, and align the crankshaft sprocket timing
mark with the timing mark on the front case.
4. Keeping the tension side of the timing belt tight, fit the timing
belt onto the crankshaft sprocket, water pump sprocket,
camshaft sprocket and tensioner puller in that order.
5. Slightly loosen the timing belt tensioner bolt to tension the
belt by a force of the tensioner spring.
6. Using special tool MD998716 turn the crankshaft twice in
the clockwise direction.
CAUTION
This procedure utilizes the camshaft's driving torque to
apply tension evenly to the timing belt. Be sure to turn the
crankshaft as described above. Do not turn the crankshaft
counterclockwise.
7. Check that the timing marks are correctly aligned.
8. Tighten the timing belt tensioner locking bolt to the specified
torque.
always before starting the engine, turn the crank clockwise by hand until all timing marks align again to ensure you don't encounter valve interference...

Here is another thread I have some information for timing belt with, may or may not help you out, and btw looks to me like your cam is still one tooth off by that pic. Looks to me like it needs to go counterclockwise one tooth

If you heard clicking then you already hit pistons on valves and even if you lined it up correctly you probably already have bent valves which is why you wouldn't have power
