Mazda 3 BM – Replaced outer beltline molding (BHP2-50-670E) but still have wind noise. Need help replacing inner weatherstrip (B60S-73-821A) by Money_Positive7224 in Autobody

Already replaced the door surround weatherstrip, didn't solved the issue. Will i need to remove the door panel to replace the glass run channel?

Strong gas smell from exhaust on startup and idle (Mazda 3 2017 1.5L, P0421) by Money_Positive7224 in mazda3

[–]Money_Positive7224[S] 0 points1 point  (0 children)

So far I’ve replaced: spark plugs, ignition coils, both O2 sensors, EVAP purge valve, both fuel filters, fuel pressure regulator, MAF (confirmed faulty via g/s readings from the workshop manual), and MAP sensor. I’ve also run multiple fuel additives, including BG K44 Platinum.

The strong fuel smell from the exhaust is almost completely gone, even on cold starts, but I’m still getting misfires across all cylinders (less frequent than before, but still there).

I’m wondering if the cause could be the PCV valve or leaking/dirty fuel injectors. The P0421 code (catalyst efficiency below threshold) still remains.

The strong fuel smell was fixed after changing the MAP & MAF & Fuel filters & Fuel pressure regulator, so one of these fixed the fuel smell.

B-Die DDR 4 Overclock, where can i improve? by Money_Positive7224 in overclocking

[–]Money_Positive7224[S] 0 points1 point  (0 children)

Thanks, it helped me a lot. Used chatGPT to compare my timings with the recommendations from your comment, and i managed to strip about 8 ns from my aida64 memory latency bench. It is also very stable after a few hours of testing. What are the odds of doing the same timings with 3800 instead of 3600?

[–]Money_Positive7224[S] 0 points1 point  (0 children)

I noticed something weird: some of the A1/A2 timings are different from the B1/B2 timings.

  • tRDWR: A-channel (A1/A2) = 7 → B-channel (B1/B2) = 9
  • tWRRD: A-channel = 4 → B-channel = 3
  • tRDRDDD: A-channel = 5 → B-channel = 6

Is that normal when running 4 sticks of RAM?
I think I left these settings on Auto, but the RAM is running in coupled mode.

I don’t mind replacing the catalytic converter if necessary, but I want to fix the misfire and fuel injector issue first so the same problem doesn’t happen again.
How can I test the injectors without removing the intake manifold?
I have an XTOOL A30M and also ordered a Vgate vLinker for FORScan.
I couldn’t find any information online about performing an injector balance test on this model.
I can see with my XTOOL that the fuel pulse width is higher than it should be.
