Unhappy Emergency! Running problems

:t ear:
Stored my rx8 over the winter. Had to charge the battery. Drove to get a car wash and car just turned right off. Turned back on and drove home. Had bought a new battery today, and I had to boost my battery in order for baby 8' had to tmturn on. Disconnected the cables and let it run for about 20 minutes til it died. I had tried to reset the ecu. 'turn key on' - 'stomp break rapidly til the temperature sensor jumps to the middle and back down' car sounded alot more smooth for about 15 minutes til it died.

It sucks to say but, im assuming its the alternator, and im not looking to spend money on something i need.

Pleaaaase, im in need of a second opinion!

Re-read your post again. You are telling us some tibbits, but not nearly enough for us to really work with.

Did it shut off abrupt or slowly, what RPM was it at each time, did you get any smoke, did the car get wet before it shut off the first time or while it was just on the way to the car wash, etc...



Questions we CAN answer:
Most issues that the RX-8 faces are easily answered when you post detailed, descriptive, and accurate explanations of what symptoms you are having with your RX-8. Many of our issues share common symptoms with at least one other issue. Several of the really common issues share MOST of their symptoms with another problem. So when you post: "power loss?" We can't really tell you what is going on. We can only throw the book of possible issues at you for you to figure out.

The amount of assistance you receive is DIRECTLY associated to how much detail you provide!

So what do you need to share?

A) Break each issue you are seeing out by itself. For each of these issues, detail what RPMs it occurs in, and what RPMs it doesn't. Detail how much throttle you are giving when it occurs.
B) Detail what the ambient temperatures are that you are seeing, what the gauges are doing.
C) If you have a CEL, GIVE US THE CODE! (most auto-parts stores will pull the code for free for you. Otherwise, you can buy a code reader for LESS than the dealer's diagnostic price, giving you a discount on that one, and free code pulling for the rest of the device's life, across every car you own) (Hint, search with Google and site:rx8club.com <CEL> before posting. You will probably find your answer.)
D) Detail any possible modifications or repairs that have been made within the last 3,000 miles, even if it seems like it's not related.
E) Detail the age and mileage of the car, and what maintenance history it has been on. NOT just "it's gotten regular maintenance" because there are wear items that are not part of "regular maintenance" for dealers and most shops.
F) Since many issues are ignition related, and you are going to get asked, give us the mileage and age of ignition coils, wires, and plugs.
G) Detail out when it DOESN'T happen. This is just as critical as when it does!

Another thing to keep in mind is that unless you are being a complete jackass, and unless the person responding to you is ignorant about the issues, our answers are going to be pretty accurate, if not dead on. Even if you don't like the option. We have no stake in your finances, no stake in making money off of it. We DON'T like to see unhealthy or busted 8s. So if you choose to ignore our recommendations, do so at your own peril, and don't come whining to us that you shoveled money at the problem that was completely unneeded.

sorry,

in reply to:

It shut off slowly, idling was averaging at 800-1100, No smoke, Car was dry

Try driving it for ~10 minutes, shutting it off, waiting a minute, driving another 10 minutes. If it seems to be getting better, it is likely the reset fuel trims not giving enough fuel at idle, and the drive is helping the ecu relearn them.

you can take the alt out and have it tested at most parts stores for free.

put an AMP CLAMP and measure DC amperage on the B+ wire from the alternator. You should be getting at least 35-70A at idle.

Wow you guys are in a good mood.

At the very least the OP deserves to have all the responses given to him in the same shitty grammar, spelling and format as that of the question.
