Rich and lean at the same time?

baine21225 · April 7th, 2009, 01:10 AM

well, when I'm at idle my A/F ratio is about 16:1, not too horrible for idle....but a lean mixture nonetheless however; its spews gas out of the tail pipe? not like dumping, but after a min or two you can start to see the moisture, this does not make sense to me? Any ideas?

Condensation ...........

combustion reaction:

fuel + air = heat + CO2 + H2O + harmfull other gases

its most likely water...

My cars like 14.8 to 16.3 at idle... depending. Cruising anywere from high 13s upp until 17 were you let off the gas. You seem fine man.

Whats it doing at wot?

its common for water to come out of the tail pipe just from condensation

Did you end up getting a power pipe? My car ran into some cold weather today in fl. It's about mid 50s outside lol. 2nd gear pull did 12.3 and it normaly is in the 10.3 range. Had to stop that, to lean, but it pulled so damn hard.

don't really wanna push it that hard until after the 17th, then i'll drive it hard enough to break the next part.....i did get a powerpipe, ended up being like a 12 hr job, the guy i got it from didn't give me any of the rubber so i had to go track down a bunch of stuff to make it all work, then i had my msd mounted where the pipe goes out until i can get it over to the spot where my battery is (is going in the back soon) but naturally i didn't have enough wire to move it foreword a foot so i had to rewire the whole thing.....md weather is the most fucked up stuff you will ever see, it will be 75 one day then the next be high 30s so it's warm and cold i guess?
