Use Stabil every fill up, but yes, freshening fuel my next step before next high speed test. Thanks.

99 legacy gt wagon - manual

originally in to replace head gaskets

heads rebuilt and head gaskets replaced

new plugs and wires — new timing belt and water pump

picked car up and was still misfiring starting with #2 and eventually misfiring on all cylinders

new egr valve — new ignition control module (twice)

still misfired all cylinders

after 5 returns to first shop, took to another shop (subie dealer)

valves adjusted to spec - way out at previous shop

compression test 90% - leakdown ok

FLOW ON INJECTORS OK PER DEALER

got car back - drove 800 miles all good

today per scan tool now misfire on #4 (highway speed)

had flashing cel for 5 seconds - now on solid

car tends to sit for months without running (i have 2 addresses)

latest misfire in single digit temps with 4 month old gas

no power loss - no overheating

any ideas?
