I have a turbo b16 civic that got tuned on s300 a few months ago. Everything is okay so far except when I let of the gas. When I push the gas back down to accel there is a delay. I can push the pedal down up to like a 1/2in. before the car starts accelerating. The throttle cable is adjusted correctly. It does it in everygear, but more noticeable in the higher gears. What can I do to fix this?

 

check volts at TPS make sure they are still in range? tahts all i can think of.
a delay... you sure its not just turbo lag?

 

The tps voltage and reading on hondata is correct. It's not turbo lag. I have an omni 70mm throttle body if that makes a difference.

 

Do you have a wideband oxygen sensor gauge installed on the vehicle?
If not, your going to be guessing as to what is going on.
Take the car back to the tuner for inspection.

 

I have a ngk plx and it works great. It's kinda hard to tell af since I am off the gas and of course its going to read lean, but when I ease into the throttle it goes back to the normal numbers like it should.

 

Well I messed with the tune last night in the low end where there wasnt much load. I got the car to stop doing what I originally posted when the car is up to normal operating temp. Now when the car is cold it still does it and if you are in the the rpms of 1-3k with very light throttle it seems to like hiccup. Almost like the fuel cuts off and on. It happens so quick that its hard to read the wideband.

 

get it tuned again

 

I figure out that it was the TPS. It was like the voltage would change as the car got up to operating temp. Well I changed the TPS and haven't had a problem since. Thanks guys.
