I just purchased a 1993 del sol that had an engine swap. It is a ZC non-vetc engine with a manual transmission. It only runs to about 3900 rpms then cuts out. It came with a P28-A01 ECU. I thought by replacing this with the PO6-A02 the problem might be resolved. It still continues. Any help woud be greatly appreciated.
