Smoky all of a sudden.

[PHX ATC]

I am not alarmed, but it seems as of late when I drive normally and am accelerating between shifts, I get a black puff of smoke back yonder.



There could be several explanations, but here are the specifics. It just turned 10,000 miles on the odometer, I have not changed the fuel filter, I just had the oil and filter changed, and started noticing it during normal city driving. I am not romping on it unusually hard at all, in fact I am quite solemn in town. My mileage has dropped for two tanks from 20. 4 to 19. 8.



Any ideas? I am running a little experiment now with this tank of fuel by not romping on it at all, shifting at 2000 rpm and going extremely easy on it.



I'll post the results in about 5 days when I refuel.



Thanks in advance.

My first inclination would be the air filter. It is either clogged up, or has collapsed in the housing. Dont forget: smoke doesnt come from just too much fuel, it is from not enough air.

Weather is warmer.........

I can smoke much more in hot weather than cold. Even in San Diego where it doesn't get to freezing it makes a difference.

Been getting a little black smoke ever since I installed the EZ. Bet if you unplug your EZ the smoke would go away!

EZ will do it, but warmer weather will too. Mine smokes more in the summer, runs better too.
