Possibly: your mixture is probably wrong. The air mass meter measures how much air your engine is taking in. However, if your flame trap hose is corroded and admitting air, then your engine is getting more air than the engine control thinks and the fuel/air mixture will be wrong. The O2 sensor in the exhaust will help correct this somewhat.

Get the replacement parts to set things right. Use a really bright light and heck all your vacuum hoses and rubber fittings for corrosion: these are famous for hidden cracks in awkward or hard-to-see places. These repairs are easy to do.

If the mixture is incorrect long enough your catalytic converter will fail. You don't want this to happen: a new one costs over $800! This happened to me: 2 of my rubber fittings (cost, under $3 total) failed, I didn't catch it in time, my catalytic converter MELTED and I had to buy a new one. OUCH!

Good luck.
