Drove myself crazy the last few weeks. Towards he beginning of Dec, I noticed that the battery would die if I let the X sit for like two days. Then a couple of events that required some serious charging and jumping. Never had that problem in the cold before. Battery I last got for it was about 8 years and a lot of mileage ago. No bigs.
Jump it from the house, since it wouldn't fire, and it's running rough as Hell. Popping Ye-Olde-CEL-of-Doom and so I decide, time to get a new scanner to replace my broken one too. So new scanner since this is more important than a battery: Find a cylinder 3 misfire, Dead Bank 2 O2 sensor #2
(known about that for awhile), and a random unconfirmed knock (which is usually there). So I go to the plugs. With some help from my little brother we get #6
in two hours later. Job took way longer than usual because of Lucky #6
and some serious gunk buildup around 2 and 4's "tunnels" to those respective plugs.
Get paid and decide to get my battery and O2 sensor since my low mileage due to these problems is killing me fundage-wise.
Today I fire it up to go do things and it gave me the similar rough run, no CEL light, and I didn't pull codes because whatever. I decide to skip the detailed troubleshooting and do the plug wires (which have been in there since I bought the vehicle in '07), dizzy cap and rotor (which the rotor looked worn as it should, the cap looked fine to me). One trip home and no issues, slightly smoother than usual running.
After it sits for 6 months while I'm in Japan I need to plan and purchase everything for timing belt replacement #2
. It's coming up very quickly.
