For the first time since I've had the '97 Cobra, I ran a diagnostic through the OBD-II to see what the check engine light was about and I couldn't make sense of the problem. Says "Code:4011 SAI Upstream Flow Error". I disconnected the wiring to the pump, re-tried, then it gave me "Code:4012 Electrical connection Error (or close to that)". Plugged the pump back in and it gave me the 4011 code again.
Do I have a failed electrical smog pump or is it clogged somehow? Local Ford parts center says a replacement pump is $215.
