1993 Mazda RX-7 — tires or pads first for a beginner autocross season?

If it were in my driveway, move a coil or plug on the 1993 Mazda RX-7 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. That's the sequence I'd use. I'd sleep better after that step, even if it finds nothing. I'd rather look cautious in this thread than stuck later.

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 1993 Mazda RX-7 is losing coolant with no puddle. That's the branch I'd chase this week. If you share a photo of the worksheet, easier to sanity-check. That's coming from doing this as an owner, not a shop. Not driving it hard until I know more.

Log the conditions before you spend. Loaded-suspension checks on the 1993 Mazda RX-7 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. On “7 — tires or pads first for,” that was the fork that mattered for me. That's the sequence I'd use. This is the filter I use when the thread starts repeating itself. I'm in no rush to be a hero on it.

Start with the test that can prove you wrong. Loaded-suspension checks on the 1993 Mazda RX-7 catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. That's the whole play. Your commute and mine probably aren't the same, but the test still applies. I keep a notes app thread for this now.

I'd want a measurement, not a hunch. Get a real battery/charging test on the 1993 Mazda RX-7, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. Time, temperature, and whether it's in gear are the notes that actually help a shop. I'd rather look cautious in this thread than stuck later.

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 1993 Mazda RX-7 does it — then decide on parts. Save the big job until that test fails. Write the result down so the next test isn't a repeat of the last one. Make the next action something you can finish this week. I'm keeping receipts and dates in one folder.

Intermittent stuff lies if you only catch it once. Swap the cheap/easy piece first on the 1993 Mazda RX-7 and see if the fault moves. Don't erase codes until someone who can help has seen them. On “7 — tires or pads first for,” that was the fork that mattered for me. Stop there until you know. If this is nothing, great. I want that in data.

Log the conditions before you spend. Get a real battery/charging test on the 1993 Mazda RX-7, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. On “7 — tires or pads first for,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' If your situation is the opposite, ignore me. Trying not to diagnose from the couch.

I wouldn't throw parts yet. Capture voltage while the 1993 Mazda RX-7 is actually failing — after it restarts you've lost the clue. Don't erase codes until someone who can help has seen them. I'd want a dollar figure or a measured spec, not 'should be fine.' Only after sitting overnight so far.
