RE: Need HELP now!!!!
that car kind of has a rough idel like it has a cam in it, both banks lean(meaning 02 sensors detect more air than fuel
1. Take out both 02 sensors ! but leave em plugged in. See if your Idle, HP, and Torque is better. If so your cats are bad.
2. If not, unplug the O2 sensors, set your voltmeter on the 12volt scale, put O2'S in a vice or or ground, put a torch on them and after 3 minutes you should see the volts change rapidly up as the flame is on, and down as flame is pulled away. If they are sticking and or responding slow, they are shot.
3.Clean MAF SENSOR ITSELF, (THE SMALL LITTLE SPRING).
4. Replace and Gap the Spark Plugs.
I dont believe in Cats, unless you have emmisions.
