Poor MPG

[Mr. Red Pony]

Give me some ideas.

I checked the spark plugs (normal wear, but still good) Changed the air filter (Dirty as ****) and attempted to change the fuel filter (No external filter... Even though I picked on up from A-Z) Does the ECOTEC have a PCV valve?

I need some ideas..

what are you gettin now?

 

[Mr. Red Pony]

HUD says 24.5 per gallon but a tank only lasts 250ish. Was 350ish per tank. HUD read 33.5 per gallon.

prolly since you got that exhaust you dont drive like you should. keep it under 2k on normal road and 3k on highway. should raise it up a little bit.

 

[Mr. Red Pony]

lol. Its my GFs car. She doesn't drive fast. And I got the exhaust about 2 weeks ago and the MPG has been bad for about a month. Its and auto btw so.. ya.. lol

There is an external filter. It's near the EVAP canister.

 

[Mr. Red Pony]

Under the hood?

Under the hood?

Nope right behind the fuel tank. Above the rear axle.

 

[Mr. Red Pony]

I looked there. I had it on a lift and looked all under it with no avail.

I've seen that. I looked in that area. Followed the lines from the tank to the edge of the engine bay.. Nothing.

Not all the 2007 and up have the external filter some have the filter in the tank on the fuel pump.

 

[Mr. Red Pony]

I know. Just proving mine doesn't have it. I will have to end up replacing the pump to change the filter. I hate in tank filters.

 

[YelloEye]

Wtf?!? Strange....So the only fuel filter you have is the sock on the end of the pump?

 

[Jmesl8er]

Mines in the tank as well

 

[Mr. Red Pony]

Not just the "sock" that hangs off the end. It also has on in the sending line right before if leaves the tank. Some pumps, you can rebuild and put a new filter on. But if you have the pump out. Just replace it. The car has 76k on it already so why not.
