Subject puts it in a nutshell.
Background - car was brought to me with a bad water pump. Replaced water pump, and at same time did a A/C service (new compressor, drier, orifice). Car drove off, made it about 2 miles. Heard a POP! and it stalled out, wouldn't restart. Back it comes. Pop was a backfire, ICM melted down. Replaced ICM, ignition coil, plugs and plug wires. Car starts, runs great - at idle in park. Drop it into gear (any) and it starts stumbling a little, then ultimately dies. Replaced IAC with no improvement. WTF? lol.
Any ideas?
Thanks for any input!
