Take it to a dealer and let them check it out by plugging it in then checking the mapping of the computer ,i suspect a fault with the ECU but its difficult to tell without the right software .remember this mapping will be encoded to stop people like me reading the faults

Does this motor have the equivalent of crank-trigger ignition? If so, is the sensor A-OK?

Either the sensor on the air filter needs to be cleaned. Easy. I've done it myself. Or one of the sensors, before and after the catalytic converter, needs to be changed. difficult.

You need to check for engine codes to see what is wrong. Bring it to a parts store for a free scan for codes. The check engine light indicates a problem, probably the emissions system, which is causing the poor performance. The parts store will plug a hand held scan tool into the cars diagnostic port (usually located under the dash) and 'read' any codes stored in the cars computer. They can them tell you what code #'s come up, what they mean, and how to correct the problem. If you have any questions after that, post them here w/ the code #;s for further help.
