View Full Version : 28 pin 059 FS?

Looking for a known good one or a cheap one I can send in as a core for refurb. Ive eliminated most likely issues including testing the CTS at several temps, the cabin air temp sensor, non-gasket related air leaks, plug wires, cap and rotor, confirmed relay functionality by using several new spares, grounds etc etc etc, replacing the dual pumps with a single in tank pump and if that isnt the ticket Ill be looking at the ecu next and if not that then injectors themselves even though they are relatively young bosch replacements (realized as I typed this that havent confirmed that the injector O-rings are in good shape). the pumps and ECU are factory OG.

Much appreciated and any suggestions welcome.

edit: problem is poor idle and stable RPM/no load quality. Miller MAF and chip installed.
