Update well last night i went to napa and got some tb cleaner and electrical cleaner gave the old maf sensor a good cleaning and it did help not with the prob i had but i noticed by my butt dyno that it had better pickup so thats good.Now as for my ongoing prob with the idle it is in the 700 to 750 mark at an idle but i keep getting like a popping noise from my exhaust it seems to happen more as the car is comming down off of rpms to idle for exaple at a stop light it calms down a bit after a long idle but its still rough and i have noticed some black carbon on my pipes though not alot its still their . could the DPFE sensor be doing this? im at a loss
