How DUMB can I be ,Makes me wonder

[asphaltguy]

I was trying to pinpoint what the troble could be with my 2000 Boxster.Well in trying diffrent things I took the connections off the computer in the rear truck with the battery CONNECTED.Now I think I have shorted the computer out .It wont retain the the program tp make the car throttle up.It will start and run ok up to 1,600. RPM S The car needed a new fuel pump to get it to start now it starts fine but wont throttle.So where would be the best place to look for one of those computers .Any ideas or can I get this one repaired HELP .Thanks alot

I never came across a Dme that got amaged just cause you disconnected the connectors while battery is connected, maybe with the key on. Anyhow its always a possibility. Look at the attachment, and if you do need a dme well then if you do not have a Pst2 tester and Ipas codes then you are in over your

head. Of course there may be other causes for your problem but you need a good knowledge of how the engine management system works.

good luck,

Agree with the above.

We have a local owner who use to disconnect the DME all the time to turn of the check engine light. It was easier for him to do it that way rather than disconnecting the battery.

When my DME was replaced 2 years ago the battery was hooked up during the replacement.

Wow thanks guys maybe I didnt screw things up .The mechanic that put the fuel pump in had a scan tool and he could program the tool so the motor would throttle up and runn as smooth as it should.Then when I turned the key off something lost all it had from the scan tool .It wouldnt throttle up the next time .Guys I really appreciate you trying to help me .Thanks

Well ,I was wondering if this could be anything to with a security of the car maybe theres a reset or something to do with that.Its just a thought .I have also been told on the computer that if it can be fixed with a scan tool then its not the computer .They are telling me that if it was bad it wouldnt beable to be running right with the scan tool .I also unplugged the mass air flow sensor .Could it be that by chance .Thanks for any help .....
