Bad Gas Mieage/Cutting Out

[LS/Vtec]

you could always throw a s300 and datalog everything. unless you have a nice snap on scanner or something similar that can do live data.

If this were my car, id start simple.

Full tune up, even if it doesnt need it, it prolly needed it.

Good grounds

Swap dizzys

swap injectors

clean filters

check compression


But none of this will help if you have a hurt motor, so check the compression.

I've done a lot of that. I haven't had my car for 2 1/2 months so I don't care anymore till I get it back. I'm sure my compression isn't the best because the motor isn't the healthiest. I'm not worried about the mpg anymore. I just wanna figure out why it's cutting out randomly. I'm gonna try a differ harness and a new dizzy when I get the car back.
