My check engine light comes on and off, and when it does stay on it goes away as long as i keep giving it gas? What could the problem be?
Oh and I'm also having an oil problem. I keep having to put oil in it every week cause the oil light and buzzer goes off. But there are no puddles of oil anywhere when the car is sitting.

 

Dump the CEL codes and see what caused the light to come on in the first place. Dumping the CEL codes is a bit of a PITA for an S4, but it can be done. The OMP injects crank case oil into the combustion chamber in normal operations, but a quart a week is too much. Normal engines under normal operations require at most a quart in 1000 miles. Check your compression. Sounds like a blown seal.

 

If the blue vert in your profile is the same as your car in real life, then dump the CEL codes.

Thats how you do it.

 

if the engine light stays off when you're on the throttle then it is caused by the tps.see if it's adjusted to spec.if it still stays on when you lift off/off the throttle,replace it.

 

blown seal already?! I just had the engine rebuilt maybe 3-4000 miles ago. the guy that rebuilt it does rotary performance so im sure he knows what he's doing...I hope that's not a seal....it was 1800 for the rebuild

 

If you recently had it rebuilt, then it's probably not a blown seal. You didn't mention the rebuild in your original post. Still, a quart a week is too much. Something is loose or broken in the oil/lube system. No oil puddles you say. How about smoke when the car is running. A bit of smoke at startup is normal. But then again, I wouldn't expect to see a recent rebuild smoking.
