Rx8 Won't Idle/Stalls After Battery Disconnect FIX

[@Drivenbymadness]

Not all rx8 models will get the oil pressure switch to move, so if you pump the brakes 20x and the switch does not move, its OK, as long as you pumped fast and hard it did what it had to do :)

[@philippos6290]

Ho buddy..may i ask?did tou lowered your RX8 or is it wearing stock suspension?it looks lowered..

Truly amazing, worked brilliant as shown in your video, thank you so much, cheers.

[@ilianamedina6738]

Driven By Madness with the ignition at acc not engine running I pump the brakes 20+ times no oil gauge jumps but the check engine light blinks like 3-4 times and it worked thanks , now the car idles much better 👍🏼

[@3mando339]

Mine does not start without clutch engaged

[@ThePolluxofLard]

This will also reset the eccentric shaft sensor and should ALWAYS be done if u change the pulleys or the ignition coils!! If you let the car idle, turn on all units that consume power like A/C, all lights, radio, heated seats etc. This will set the idle to a perfect operating speed, even if u use a lot of energy and the alternate has to produce a lot of energy :)

[@terrelljohnson3639]

Driven by Madness I return to you 5 years later! Thanks for uploading all these videos. Just had to replace a battery and alternator and ran into this issue. I did the 20 break stomp but still stalled. Did it again drove it and stalled again. But after I think the 4th attempt it help idle at start without me using the gas. Guess it just needs to be done a few times.

[@waltercollum6254]

With little to no info on when my oil change or tune up was done, and the truth of the claim to a rebuilt motor with no proof, this video was of great help. Thanks!

[@dustin8470]

In some cases you'll also need to clean the throttle body before you do this procedure. Great explanation of the idle learn procedure.

[@archieone3710]

It sure did work after 20x brake pumping,but no gauge level going up and had to completely press down my clutch to be able to start the car but 25-30 mins of idle and restart no revving touching did the trick ! Great video and info@driven by madness !!!!

[@Mickeyt57]

Having this issue but cannot keep the car running. It dies if I let off the gas. New plugs, coils check out fine (new ones on the way regardless), checked wires, tps/throttle body, eccentric shaft sensor, fuel pump, fresh fuel. Compression tester on the way, but seems fine (when the engine starts, it fires up immediately barely any cranking, strong pulses with plugs removed). Checked for vac leaks, cant find any. Double checked all electrical/fuel connectors... I'm lost on this one. The engine runs and drives great, just stalls at idle, and then wont start for a couple hours after but i'm not sure if its flooding as I don't smell any fuel even on the spark plugs.

[@johann947]

Mine doesn't do the oil pressure indicator thinghy even if I press the brake pedal like I'm a cocaine addict. Does it need to be in gear? I saw in your video that your car was in gear. Regardless, this is the other procedure that I know of, written in very simple, very easy to understand steps: 1.keep the odometer button pressed (the one used to reset your current trip / the tiny plastic tip that sticks out from your dashboard) 2.slowly turn the ignition key until the dashboard lights up 3.keep holding the odometer button pressed until the odometer display (km/mileage indicator) says "test" 4.keep holding the odometer button while turning the ignition key to it's lowest position (off) 5.keep holding the odometer button while slowly turning the ignition key until the dashboard comes on again 6.keep holding the odometer button until the tiny display says "test" again 7.keep holding the odometer button while turning the ignition key to it's lowest position (off) 8.release the odometer button and turn your car on normally. Or with some kinky toys. Spice it up. I don't care.

Mark Rainier Dela Vega Mine is a 1st gen RX8. Production year 2003, so it is one of the first ones. I have two ECUs for it. The brake pedal doesn't move my oil pressure indicator, no matter what I do, regardless of the ECU. At least the second option works

[@essexrotary1540]

sometimes you need to press it more than 20 times... i have seen some cars that need to pump the brake like 30 or more pumps.

[@edmusick7794]

Ok but what does this procedure do, what does it reset? I just changed the battery and my 8 won't idle even after a 150 mile trip.

[@paulvernon4160]

@@edmusick7794 I would disconnect the battery again, clean the maf sensor, leave battery off for a couple of minutes, reconnect, then (making sure car is stone cold ie first start of the day) start car (when car is cold the revs will be increased so shouldn't stall whilst relearning) let the engine idle for 20 minutes without using accelerator (car shouldn't stall, but if it tries to just us the accelerator the minimum you have to) after 20 minutes turn steering wheel full lock to full lock left to right, then turn off, then turn on and go for a drive.

The BHR Midpipe is one of the best you can get. It provides a nice deep tone but doesn't make the exhaust much louder than stock. It is a bit more than other notable de-cats like RacingBeat, but it doesn't become raspy overtime. Also make sure to check out the RX8Forums, especially the new owners thread to learn the pros, cons, and everything in between about the car; since you are a noob ;) Good Luck!

Thanks it really helped

[@edmusick7794]

Hi my 2004 6-spd RX8 doesn't respond to the brake pedal technique. I just replaced the battery and apparently the ECU forgot everything? My Mazda mechanic told me I had to drive it 100 miles or so to remap it, that's going to be difficult to do in traffic, stalls at lights and the infamous numerous starting attempts to fire it back up. What do you recommend?

[@edmusick7794]

Well I drove it 150 miles tonight and it still won't idle. WTF is wrong with it, was fine until I changed the battery?

[@FearTheKnife]

Sometimes it will take multiple driving cycles and multiple conditions of driving i've noticed to make it as good as it will be. This info may help you as I own a 2005 rx8 6 speed and it does sweep the oil gauge, however yours may be to old to actually do that. 2004-2008 Method 1. Turn ignition switch to "ON" position, but do not start engine. 2. Pump the brake pedal at least 20 times within 8 seconds after the ignition switch is turned ON. NOTE: Manual transmission equipped vehicles produced after VIN 40132647 and automatic transmission equipped vehicles produced after VIN 40132607 or vehicles with PCM updated to "L" calibration or later can confirm the clearing procedure was performed. If procedure was successful, the oil pressure gauge needle will move to right of center slightly (nearer H). Vehicles produced prior to these VIN's or vehicles without "L" calibration do not have an indicator to confirm the clearing procedure was performed.

[@edmusick7794]

@@FearTheKnife I had Neptune Speed conduct a compression check, Front rotor 45% compression, Rear rotor ZERO compression. Having a new factory engine installed, new coils, wires and spark plugs and new radiator too, Yoshi found a small leak in it this morning.

[@FearTheKnife]

Yea that makes sense I found a 2005 Rx8 with only 38k miles and let me say from experience the ignition stock sucks, I checked the plugs just on a wim and found one of them solid black, I had a burned out coil even with only 38k on the motor, after buying 4 new coils and plugs ect the cat shortly after failed and gave a check engine light probably from accessive unburnt fuel. The most surprising thing is the car ran fine even with a bad plug and coil so it goes unnoticed fairly easy and can cause a lot of damage.

[@FearTheKnife]

Also one last thing, I would find it unlikely that the rotor would have absolutely no compression as I'm sure one of the 3 faces would have something. And I would think the car wouldn't even run at all with some values like that. Hopefully everything turns out good for you and there not just running a train of repairs on you.
