First start in the morning or a cool engine I see white smog coming out of the exhaust with no pressure from both pipes. With the cool engine I notice 10 seconds of uneven idle. other wise work well, it has a new set of spark plug and radiator recently done.
Thanks,
Ricardo

white smog is nothing to worry about, try cleaning throttle plate on both sides and iac hole with choke cleaner.
