Thread: weather affecting drivability?

so drving home from work,i notice my nx is jerking on light throttle less than 15%(read by safc2)....any more throttle it doesn't jerk or sputter....

its jumping to 16 on my aem uego when it jerks ...under cruising conditions only and the car wasnot fullt warmed up either...but once warmed up same issues...

my question is...does this warmer weather affect how it runs?? seems llike it since ive streeet tuned it and its now like 70* versus the 40* when i did a lil street tune

WOT im 12.7 to 13.1 all the way to redline...im kinda wondering what it is...

i adjusted my fuel settings and made minimal differance...even on the second data file,with no settings on (all 0s) it gets wonky under light throttle

and tips or possible ideas.



just got home and parked the car and smell a little bit of fuel...hmmmm

sounds like your o2 sensor might be on the way out.

Some people re-tune for different seasons but i doubt that is your issue.

Double check all your connectors.

Thats kinda what I thiught...o2 is a 4wire and gounded to the,im....abot 2 years old


But jnow I remember I put in some bosch 4 tip shit sparkplugs a ehile ago(got them 4 free).... Gonna put some ngks back in.... Forgot whick ngks for a VE...

that's the point of fuel injection, so we don't have to compensate for changes in weather or pressure.

Bkr6e is what i run n/a in the VE

nice,.
going to grab some plugs tomoorw .put them in and see if it helps..im also going to replace cap and rotor...i think it start here and just work my way..i havent replaced a whole lot since ive had it ( 2/8/10 till now 2 years) beacause luckily it is reliable for the most part

i drove it again and it only does it from 9-15% throttle at only 1800-2400 rpms...hmmm... but wot it still 12.7-13 afr

I had the same exact symptoms when my o2 sensor went bad. My wideband read around the same 16 range but it was fine at WOT. I replaced the o2 sensor and it was fixed.

Those people have no idea what they are doing with a wideband and an 02 sensor then to keep it funky. Once you get to know the safc and get really good with it you can literaly be driving down the road and fine tuning at the same time (hopefully in a no traffic area). You can lean your car out for better gas mileage while driving down the highway on the fly in about 10 second once you get the strokes down. I used to tweak my tune alot till i got it perfectly where i liked it a/f wise for cruising and wot. And even then id still play with it depending on the tempature outside.

I don't know about the weather but something is defiantly up with the fuel Im getting less MPG's per tank and the car is not running as good. I'm babying the throttle too. These people keep f*cking with the formulation of the fuel, your getting less and paying more at the pump.

This is the most random post I have read all night between all of my forums....
