Does 43 mean it may be a good idea to replace the fuel filter? I just got a brake job, transmission is wearing out. Catalytic converter was replaced a few years ago. Just trying to make it last as long as possible.

Thanks. was going to pull the 7.5 backup fuse, wait 10 seconds & return it to clear the ECU anyway. I replaced the O2 sensor when the catalytic converter was replaced. I have not replaced the fuel filter in a couple of years. I only drive about 10K or less miles per year, so figure I'm due & it won't hurt since it's not that expensive, plus 2 Banjo fitting seals.

I'll definitely check the fuse. Easiest & least cost is BEST! Thank you kindly.
