The car: 2001 Subaru Outback Wagon Limited (4-speed auto) with 213,300 miles. I bought it 1 year ago with 202,000 miles and I don't know it's history but it is in very good condition and appears to have been well cared for.
Maintenance: Timing belt/water pump/coolant/engine seals, etc./spark plugs/fuel filter replaced at 210,000 miles. Spark plugs are NGK platinums.
Problem: About 4 weeks ago the check engine light pops on in the morning when in 0°F. Yay. The engine did sound like it was knocking for about a minute.
After searching this site, I concluded the knock sensor needed replacing - so I replaced it about 2 weeks ago. The dash light stays on to this day.
I took it to Autozone today and plugged-in/read engine codes: 0327 low input knock sensor (bank 1), and 0303 cylinder 3 misfire.
Note: When I replaced the knock sensor, the wire broke at the plug-in connector, so I cut/spliced the new knock sensor to the wire sticking out of the harness.
Spark plug wires might be original. I'm hoping the knock sensor will work okay they way it's wired. Do I have anything to be worried about? Is the misfire caused by the knock sensor/cold weather situation or do I need new wire?
Thanks in advance for any info...
