You have a misfire on cylinder #1 and an issue with the MAF. First you have to determine if it's compression, fuel or spark that is lacking on that cylinder. For the MAF check the intake snorkel carefully for anywhere it could be leaking air. You may also want to do a backpressure test on the exhaust to look for a plugged converter.
