Hard to start when cold.
My 2008 Buick Enclave is causing some grief once again. When I try to start in when it is cold (sitting overnight) It acts as if there is too much fuel delivered. It has 160000 Kms, and I just changed the six plugs for the exact same model (AC 41-107) did the air filter at the same time too. Once the car has run, it starts ok, but is very annoying every morning, wondering f it will start up without flooding.
