How responsive should it be to the throttle? I find it to be not very responive like if i floor it takes like 3/4 of a second to respond, doesn't even seem to respond quickly if i give it light throttle either. Could this explain why the car seems like it lost power? I am wondering if I should change the o2 sensor as I think i should get better then 19mpg on a N/A. So far the engine has been seafoamed, air filter replaced, plugs and wires replaced, MAF sensor cleaned with electronic cleaner, fuel filter replaced, but with a non oem filter, PCV replaced, cracked knock sensor replaced, ECU temp sensor replaced. What I noticed though was my spark plugs with only like maybe 5,000KM were very carboned up and black and one plug even had sludge on the tip. The plugs were NGK G powers. This time I am using V-powers but seems to drive the same. Help is well appreciated thanks. Sorry for the long post.

Could be as simple as recalibrating your TPS. Open the hood and slowly open the throttle by hand and see if there's slack. Try adjusting the TPS a bit and try again from inside the car.

19MPG is pretty bad, but sensors are finicky things.

Thanks for the reply. What exactly do you mean by adjusting the TPS? I do notice some slack in the throttle piece.

have you reset the computer ?

Yup. Unplugged the fuse with car off. Waited 40 minutes. Put it back in started car let it idle for 10 minutes then shut it off. Fiddled around with the TPS seems a little better.

adjust/set the TPS according to this

Thank you! I was looking around your website under tech articles but could not find it.
