Apparently MOPAR had a handheld code reader and diagnostic tool that would show sensor data, and run tests on the EFI system.
Anyone have any idea where I could find one for a reasonable price?
I've looked at the Equus 3140, which reads ODB-1 computers and has an adaptor for the diagnostic port on our '87, but according to the manual it just reads codes after you turn the ign. key on/off three times. I can look at my power loss lamp and get the same info.
Are there any other handheld units (or even a PC interface) that would provide the same functionality as the old MOPAR unit?
