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.
yea mine just raced and i would be driving at 45 mph and it would still go faster, talk about scary.... turned out to be the ISC. I would have to tap on the top of it for it to go back down. $125 and 30 minutes later (easily replaced) it was fixed
