-brimbo breaks, suspensions and etc.
-Stock 2004 sti TMIC accompanied with an I/C Spray system (could be set on auto)
-6 gears electric (DCCD)
-Tuned with average boost of 1.4 bar (almost 22 psi) and timing of 24-26 (as far i believe)

-Never filled with else than 95 octane.

Hi all.

I have re-tuned the car 6 months ago and right after tuning (remap) a cam-shaft sensor code popped (hesitation on second gear on 6-8 rpm). I got it replaced with a used sensor and re-plugged it to computer then no codes occurred.

Now I am having similar problems which i doubt is linked to that one.

Whenever I want to fill it with gas, always a quarter is missed (never at full level). I asked a mechanic friend of mine who said this is because of the "canister". I am also experiencing huge drop in fuel mileage.

As well, i have noticed a gas smell, rarely, when i'm accelerating at the 6'th gear from low speed (Mph 60 onwards)

I'm experiencing stupid hesitation as well on the third gear at Rpm 6. (which i believe is the camshaft sensor problem because code has flashed for a second and went off, same old problem, which i believe because the sensor i installed was used).

Am i correct in my guess?

Summary:

-no full fuel level
-gas smell when accelerating at 6'th gear (rarely)
-Hesitation and jerking at third gear, also rarely, at rpm 6, with a fast code flashing.
-vehicle's performance is never like before.

I will really appreciate any kind of advice guys.

Thanks

Hey all, for any who had reviewed the thread, I just wanna confirm my thoughts were right as I replaced the cam shaft sensor and Canister and problems had gone.

Thanks
