did a lot of work to the sable this weekend. unplugged coolant level sensor, pb blasted the sticky iac (no change), cleaned the tb and maf, vacummed out under the cowl (never seen so many acorns in my life), vacummed cabin filter and reinstalled. also tried seafoaming the sable. not my first experience, but the first with this car. used the big hose off of the vacuum box (boy was that a bitch to get off). filled a 9oz cup up half way, and slowly poured it into the hose. shut the car off. added the remainder to the fuel tank. started the car up 10 minutes later...no smoke whatsoever. wtf? i was hoping for a smoke show and the car would feel better. no such luck.
