Hey Guys, I'm having this weird phenomena with my stock 305 TBI Engine.
On cold days it has plenty of power, I can rock the car if I want.
On warm days it seems to have no power whatsoever...
What's going on here?


Appreciate it guys!

 

Cold days=oodles of power
Warm days= no power

You're probably running stupid rich, what's your AFR numbers look like?

 

Sorry, I'm a mechanical dummy. I have no Idea what an AFR number is.

Also, I have been having some smoke on start-up, I was told by a mechanic it possibly had something to do with the fuel mixture?

 

Air to fuel ratio.

What color is the smoke?

 

Gotcha.

Color of the smoke is darker blue-ish.

 

Oh. Thats no bueno.

Blue means oil.
Black means really rich
White means coolant

Are you burning oil?

 

hmmm, not sure... It's hard to tell, it's winter here in MO, so I'm seeing normal steam clouds as well...

I do recall smelling fuel after the smoke show, or if I gun it, and immediately turn off the engine....
