So i first boosted my 240sx this past summer. all is well. started to upgrade little parts here and there.
I got a hks ssqv bov, Megan 3" dp, and 3 inch piping and changed the very restricted exhaust.
Ever since the upgrades, my idle afrs have fluctuated a bit.
before all the upgrades my idle afrs have been 14-16s, cruising 14-15, wot 11s
now my idle afrs fluctuate at times like when im at a stop it will be 14-16s and then at another stop it would be at 11s. not sure whats wrong. i know my o2 sensor is good (just changed it a few months ago) and tps works cause when i unplug it the idle gets rough.
my fpr is set at 36psi. also when i rev the motor the fpr goes up and then back to the set psi. is it suppose to fluctuate above the set psi? its a megan fpr.
any info will help. thanks guys
