:confused:93 Sedan Deville 4.9L stalling at lights, racing idle.
Pulled the codes as the service engine soon light came on.
They are: E27,E98,EE F48,F70,F85
Can someone help me decipher this? Thanks in advance for your help.

ISC = Idle Speed Control motor. Located on the side of the TB. Simple R & R. Do a search for the adjustment procedure after installation.
