Reduced Engine Power - limted to 11mph

[Paul]

Time to check for faults in the DME.

Did you fully charge the battery (over 12 hrs on a charger) before trying to reset the e-gas?
If you try what Paul suggests without a fully charged battery (~ 12.6 v at the terminals) you are wasting your time as the DME is very voltage sensitive....

Time for a new battery...buy a maintainer while you're at it. You can't let these cars sit and drain the battery...causes all sorts of problems, as you're finding out.

Thanks for all of the help, guys. How do I check the codes on DME, Paul? Is that different from engine trouble codes? I've had the battery charged and still not getting any success. I still do not hear the throttle body motor. Does it matter if I have the hood up or have the battery charger hooked up? Does the boxster have a hood switch?

Where are you located?

[Paul]

The DME is one of several computers that can post codes.



Here's some eGas codes:

Thanks Paul. I live in Ann Arbor, MI. These are p codes so they should illuminate the check engine light, no? Do you think my pedal sensor has failed? what does egas learn do? learn the minimum position?
