Need an EFI tech!

Yes, the engine was warm when the KOEO test was run...actually I have run the test several times just to confirm that it was throwing the same codes consistantly. It's been a while, but I believe that I set the TPS voltage at .96v. I don't have a spare MAP/BP sensor, but the one I installed was new and I know that when I tested the output, the voltage was in spec for my elevation.

Yes, the '93 Cobra computer was calibrated specifically to work with it's 70mm mass air meter and 24lb injectors. They will not run properly if the parts are changed individually but, if the parts are used together, than it should work just fine...at least according to Ford.

Thanks for all the input. Please feel free to chime in with any additional ideas or suggestions!

The voltage is just a carrier, the EEC actually gets a varying frequency with changes in altitude. The frequencies are 122.4hz for 17" of mercury to 159.6hz for 30" of mercury.

Absolutly, if they are all matching parts they will be just fine. #24s on a motor that is stock will run fine. I ran them just fine for quite a while. #19's are to lean in my opinion, 24's are good.
