if there is no tentioner pulley on it, then the adjustment has to be on the ac compressor, you should be able to loosen it up, pull it till your belt is tight, and tighten it back down.. unless the alternator is on the same belt, if so that is where the adjustment is.

Could be one of three things:
If the check engine light is coming on intermittently, it could be your gas. You should be using 91+ Octane Gasoline (put some octane boost to see if it smoothes out, it's about $4.00). You should be putting in Chevron/Shell/76 gasoline, not the ARCO/AM-PM gasoline. The top tier gas has additional cleaners.
Could be a bad coil not triggering one of the spark plugs.
Could be the camshaft position sensors.

You need to have an OBII scan (fault scan) done by a dealer or a specialty shop. It'll pull up faults and point you at what needs to be addressed. Sometimes it's a loose connector or moisture intrusion. Other times it's a simple part replacement or "timed maintenance" IE: O2 sensors etc.. It's your onboard computer pre warning you of future possible problems.
