MAF ground.

First off I did do a search and didnt find what i was looking for (i could just suck) but here is my problem.

My car isnt doing to well on gas right now (18-19mpg) on a stock KA24e it was recently rebuilt so only has like 13k miles on it. I shift at around 3k rpms where ever i go. It has a recent tune up (sparkplugs, wires, ect.) So i started checking sensors and heres what i have so far.

MAF: battery on: Ground - .04 volts, power .87 volts car running power 2.6ish at 2500rpms

Coolent sensor was 316ohms at operating temp.

and i havent tested my O2 yet.

But my main question is can I can run a ground from the MAF to the battery to get the voltage down. I will leave the one ground i would just add one. Would this work to fix that issue? Also does that coolent sensor resistance sound right? Thanks for the help.

run your extra ground to the intake manifold where the other ground lug is bolted on.
