I installed new seals on the injection pump on my wife's '01 Beetle because it was leaking. Everything went fine, I re-primed it with a vacuum brake bleeder. It starts and runs great, and even idles fine cold, until it warms up, then it idles rough, but still runs great when you rev it up. I changed the fuel filter thinking maybe that was the problem. Also, I don't think it's an EGR issue since I bypassed that a few years ago. Any help or advice will be appreciated.
