When coming to a stop the tach bounces from 12k to 0k rpms before settling at the normal 7k at idle. Sometimes when it goes to 0 rpms it dies.
TRY THIS AND LET ME KNOW IF IT CORRECTS YOUR PROBLEM
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake
is the air intake hose the same hose the maf sensor is attached to?
Yes wwmcgee it is.
OMG Dennis... Thank you very much. I had the exact same thing happen just recently and followed these steps. Thought I would try this first before replacing the PCV or MAF sensor. Worked like a champ. Idle is taking a few to learn but 90% better so far. Thanks to both for listing and posting solution. Hope this update keeps the post alive a while longer. PEACE!!

My mistake, I meant 1200 RPMs and 700 at idle
Thank you ....I'll get this a try.
Thanks for the help. My tach still bounces but it doesn't die anymore. I will use the other half of the can of intake cleaner, maybe this will make it even better.
Thanks again
do u know that 12 K means 12 thousand RPM?,
