Engine Timing Correct?

1998 Honda Prelude Type SH 2.2L 112,000: I had my timing belt replaced and have been having issues since such as stalling when coming to a stop (took it back and he just turned the idle screw) then I almost did not passing smog due to high hydrocarbons (I was like 8 ppm away from not passing and everything else was low) and the check engine light started coming on every once in awhile at idle. The code is for a misfire (cylinder 4, 2 and random). Oh, also it has been making a whining noise on acceleration/deceleration. I thought it was because the belt was new, but now I am wondering if the belt is too tight because it has been a year. I'm not sure if I trust my mechanic to thoroughly investigate this as he has gotten really busy the last couple of years and doesn't seem to care anymore. So my question is how can I make sure my timing is correct? Can I tell by just removing the valve cover or do I need to take off the timing belt cover? I would take it to another mechanic but I don't feel like paying hundreds of dollars to check out if my mechanic has made a mistake. Thanks!

To see if the engine is in mechanical time, you'll have to remove the valve cover and set the engine to top dead center #1. The timing belt uses a hydraulic tensioner that automatically adjusts the belt's tension.
There is also a balance belt before the timing belt that is pre-tensioned by a spring loaded arm. The balance shafts are timed in relation to the crankshaft. Once the pretension is set by the spring after installing the belt, the arm is locked by tightening a nut.
The noise could be from any number of things. You could start by removing the accessory drive belts one at a time to see if the noise goes away. If you remove all the drive belt and the noise is still there, it is probably behind the timing cover.
Suggests that you pick up some service information if you haven't all ready.
