AF82F01024. K21 engine. Electronic. Putting when cold start with accel all the way down. Once it warms up it runs fine. Changed regulator due to by-product sludge coming out. Cleaned fuel intake components. Changed plugs and coil packs. Did pedal dance to clear codes, learn, calibrate. Runs good when warmed up...?? Injector? TPS? Stumped. Expensive guessing.
