Yes it is. Husband thinks it a head gasket. It you take off the radiator cap with running it 1/2 hr. Or more it just keeps bubbling?/
code readout from autozone(aa random cylinder misfire detecked.
aa1-fuel system concern
aa2.-Ignition concern
aa3.-MAF sensor faulty
aa4. HO2s/AF (heated oxygen sensor/Air fuel) ratio sensor fail
aa5- blocked intake or exhaust system(this code only came up once? Augh!

If you get a head check done, this is a simple chemical test for co in the cooling system, this will prove one way or the other if the gasket is a problem, the bubbling is a concern, so I would go get this test done, it takes about 5 minutes to do.
