    Got a surge going on.

    Have a surge in my D2 TD5 when coasting (intermittent) goes away at WOT and has rough idle. Maybe over fueling on boost and under fueling off boost. Not the MAF. So would think Fuel pump, fuel pressure reg or MAP. Anyway to pick between them.

    Or oil in the harness? Boy, those rattlers (as Pedro would say) have problems.

    No I replaced the harness a few days a go as it had a bit of oil in it. No change to the problem.

    Oil at the ECU Plug can cause the same issues , Even thou you changed the loom in the head the red plug at the Ecu should get a clean with some contact cleaner also where the loom from the rocker cover meets the main loom
