Hi, I posted my question in June this year. Daniel suggested to use TriFlow to lubricate the valve and use RedLine Fuel System Cleaner. I did it as Daniel had instructed. Both cars are running fine now. Thanks a lot Daniel for your help! BTW, I could not find Berryman B-12 Chemtool Spay in Ca.

================ Thanks for replying back. Chemtool was scarce for a short period of time -- seems they needed to alter the formula to comply with air quality regulations, but now you should find it widely available again. I'm in Southern California and I see it at AutoZone, Pep Boys, Kragen, etc.
