D-Jet does not have a MAP sensor. Are both of the MPS' you have correct for your 1970 car? Part number should end in 049. Also have you confirmed that all components of your D-Jet fuel injection correct for a 1970 car? They are listed here: https://pbanders.synology.me/914/DJetParts.htm Have you tested the MPS' and of so, how have they failed? |
