Vtx 1800c wont idle, new plugs, wires ok, no fi light codes, runs ok at high speed, pops at low speed, cleaned out old fuel with injector cleaner.
AGREED, had the same problem; hesitation, skipping, popping at low speeds. Ran good w/ new plugs for short time. tried injector cleaner. No FI codes. Dealer couldn't figure it out after $200! I replaced the $26 fuel pressure regulator and she runs Great!!

Fuel pressure regulator, NOT jets, ecu or plugs
The problem was the fuel pressure regulator, not the jets, ecu or plugs or wires!
