I was running a poker run last weekend. I put in 02 sensor bungs to check a/f ratio. one of them rattled loose and was blowing exhaust into my carb and the engine compartment.

dumb question but could i lose 3-4 mph from that?

I suppose it is possible. That condition would pump hot, corbon monoxide into the carb rather than O2. Gotta be worth some power..

BajaRunner,
Yes. Exhaust contamination has a very adverse effect on output, especially in enclosed areas. Isolating spent charge is critical IE during dyno testing.

sure you could loose a couple mph in oxygen deprived environment...

I had a 02 plug unscrew itself out of my "bung hole" at hot boat weekend last year,boat immediately slowed down (about 5 mph) and was making a awful racket that sounded like broken valve train. So in my experience,yes,it would slow you down. Didn't it pop and make a awful racket that sounded like something broke? Smitty

Yes,

i pulled over and found it, but was 50 miles up the lake, so i just turned on my blower and drove it back. but it was making some noise.
