Bad starter relay or a bad ignition switch will keep the starter from engaging via the key.
Code 27 indicates a problem with fuel injector #4. This would explain your sub-35 MPH issue.

I believe this code is not #4 specific. Check the harness and the plugs on the injectors. Basically what it means is a plug or harness prob at one or more injectors or 1 or more injectors are bad or clogged. Try some Techron Plus or Lucas Fuel injector cleaner (I personally like the Techron) for a couple tank fulls and see if it clears up.

You're correct, I didn't look far enough down the list to see that code 27 is listed multiple times, covering all of the injector circuits.

And BTW kgriggs75 (http://www.automotiveforums.com/vbulletin/member.php?u=430281), Try the relay first, then replace the ign. switch. Once you get it to start properly, the other prob might go away.
