2004 RX8 hard starting issue ???
http://www.mazdaforum.com/forum/images/icons/icon1.gif 2004 RX8 hard starting issue ???
I am having issues starting my RX8 sometimes, it takes several tries to get it to start. I am guessing the plugs may be fouled but I will change those out and see what happens. Any other ideas |
Plugs, wires, coils, starter, compression, ess, battery, electrical grounds, fuel injectors, fuel pump, fuses (many), immobilizer, keys....I think that is it.
Without more information, we can't really narrow it down more. 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. |
my guess it's either plugs, a weak starter, low compression. But I have my suspicions about how fast the starter is turning. I did read that there was a TSB on the starters on the earlier models not having enough a$$ to turn the motor fast enough to start em.

compression, coils, plugs, plug wires... how many miles are on it?
|
I changed the plugs and it fixed the problem, I still think the coils and wires could be done as well but I really dont feel like sinking any more $ into it now.

Coils, plugs, and wires fail about the same time. 'Not feeling like' doing proper maintenance is neglecting your car.
And when one of these parts fail the additional failures snowball. A coil fails and both plugs on that rotor will become fouled. Cat will fail quickly which will start to fry your o2 sensors and buildup too much heat in the engine trying to push the exhaust out, damaging seals and warping the housings. If you are broke, don't drive the car. If you are just poor, spend the little bit now to avoid significantly more money later. Advance Auto online has frequent sales that can drop the price of coils+plugs+wires to $182 and free shipping. Not needing plugs will drop it to like $110-120. Replacing them is 30 minutes with a 10mm socket, 4+inch extension, and ratchet. |
No RIIP I'm not poor.. I was fixing the car to sell, which I did yesterday morning. And I'm pretty happy it's gone. Don't get me wrong it's a nice car and really wouldn't mind owning one if there weren't so many inherent issues with it. An 04 with 130k+ miles is going to have issues. But thanks to everyone here for all the great info, at least I will be able to sleep at night knowing the new owner wont have starting issues and the power steering will work fine.
