I have 2 G2s and they both currently have the same problem. the idle surges between 1k and 2k. constantly. One teg stops after I drive it awhile but the other keeps doing it. What could that be?
surgeing idle
im almost positive its a 02 sensor
wooo here is a list my good man,
02 sensor, yeah it helps, try cheaper stuff first
clean throttle body
make sure u have enough coolant
make sure you brake system is functiong properly, if u stop and idle drops it could be that.
clean,replace air filter
check/replace pcv valve
fuelfilter=if old, or if u keep hitting empty and clauging the lil guy w/ dirt
sparkplugs=old?gapped correctly
plug wires
more expensive stuff would be ignitor, coil,cap rotor
its so many things hahah!
if u have cai= u will suffer from low idle once in a while no matter what!
