Can a bad MAT sensor cause a loss of power?

My MAT sensor is going bad, and I just got whupped by a 3.1 Camaro tonight, could that be the cause... also, what is a good brand for fuel injector cleaners, I still think mine are being gay... lastly, will water dripping on an O2 sensor make it go bad right away? I had an anti-freeze leak that dripped directly on the O2 sensor... other than that, the O2 is only about a month old.

Any other suggestions as to why I might be being beat right from the line to a seemingly comprable car? (he has no mods) The MAT code, and occasional (and I mean, occasional) lean O2 is the only thing I could think it is... the car has had a tune up, we both had a full tank of gas (I had plus, he had regular) and we're both automatics. His is a 91 RS 3.1 btw. Help me out here! 5 hp and 5 tq don't mean a 5 foot lead after 50-75 feet.

You should loose to a 3.1, sorry.

If you have been getting lean O2 SES codes, you should be looking at your O2 sensor if it has never been changed.

Why? We both have the same tranny, if anything i have better rear end gearing, and he's only got 5 more tq and 5 more hp. We both weigh about the same... So what else keeps me from being even with him? Is 5 hp and tq that big of a deal? Or is it what I think, that my engine is going out?

"lastly, will water dripping on an O2 sensor make it go bad right away? I had an anti-freeze leak that dripped directly on the O2 sensor... other than that, the O2 is only about a month old."

Read more carefully.

And lastly, could you answer the question about fuel injector cleaners?
