Tune up help!
My car has been running misfiring for a little while now (2 months) after I got a new engine installed. I finally decided to take it to the shop and they ran a compression test again. They said the engine was fine but I needed a tune up. They said $1041 for just a tune up!!!! I asked how much labor would cost they said around 150 so I'm just going to buy my own parts. Can someone recommend me a good tune up set or individual parts? (Coils, Plugs, Wires) Thanks in advance

I've seen good reviews on the BHR kit but I'm not an expert on engines nor do I have lots of money

I too have been looking at tune up packages. I dont know if I would trust parts from ebay, they are known for selling knockoffs as the real thing. I would check out the vendor section here on this site, check out mazmart and mazdatrix in particular. I believe both offer packages that include plugs, coils, and wires. Keep in mind the stock coils and wires last about 30K miles, while the BHR ones should last a lifetime, and improve performance. The BHR costs $580 for all three. I think the mazmart package runs about $400 (which includes all OEM parts). As mentioned I am looking to do a tune up soon as well, and the BHR seems to make sense since I wont need to replace by coils or plugs ever again.

I'm torn honestly. I cannot make up my mind. I don't drive my 8 over 5k a year so 30k is a long time. 209 vs 580?

I recently installed the BHR ignition and new plugs, and its incredible. You 'll find a lot of info about the mod and ignition health is one of the most important things for your 8. Its worth it in the long run, more reliable and I gained almost an extra 5 mpg on average. I have saved around 200$ just in gas over the past 3000 miles. Easy install and never have to worry about the coils for a while, its a win for me.

I bought a tune-up kit on eBay for $245 that includes a genuine Mazda coils, NGK plugs and wires. I paid $80 in labor cost to get it installed at a local rotary shop (Rotary Evolution). So, everything i paid is just $325 total. The car is running better than before and i redline the car once a day to take the carbon build-up away... :)

Hello, the BHR ignition is highly recommended.
I bought the BHR midpipe, couldn't afford both, so I went with OEM ignition. Advance Auto lifetime warranty coils, 4 for $125, 4 NGK laser iridium plugs for$86, and NGK wires for $33. Car runs great. Btw, misfires kill cats pretty quick. If you've been misfiring for 2 months, don't be shocked if you need a new one soon. |

I was going to purchase the same thing but I read seller reviews and there was a negative review on the Mazda oem coils? Also I read in posts that they could be lower quality. I wonder how much the dealer will kill me with the install.
It's up to you to decide, i had mine installed January of this year, and the car is still running good, did i mention its running better than before... :) Anyway, if you want to upgrade, then just get BHR... |
IMHO BHR and if you cant you need to consider if this is really the car for you.
Maintainance will get a bit costly and going the cheapest route today is gonna cost you far more tomorrow, or next week, "etc." |
IMHO, if one chooses to use OEM ignition parts, this in no way reflects on the suitability of this car for any individual owner.
I do my own work for the most part. I replaced my converter, did my tuneup, and other assorted maintenance tasks. A modicum of mechanical aptitude, a willingness to learn, and a small investment for the necessary tools is all that's required. This is where true savings occur. |
autozone bruhhhh
120 for 4 coils + a 90 day warranty if your smart you can get the coils for freeeeee or new coils every 2 months i did install my self took 10 min cost me zero dollars ceramic brake pads were also free for me |
I got the BHR coils and plugs. Pricey but still cheaper than parts at the dealer. I hope I can feel a difference for the investment. But does misfiring really ruin the cat that quickly? I may invest in a used midpipe if that's the case

If you're at 30,000 miles I bet you will feel a difference, be if from the upgraded coils or from just changing the plugs I don't know. But I know that I felt a (unexpected) difference when I did the BHR kit at 25,000 on my car. The engine felt far more willing to gain and lose rev's. As to how many misfires kills a cat - I don't know for sure. I believe once reading that a certain number of misfires is acceptable to the ECU on the RX8? What I do know is that in my previous car (a 2000 miata) coil pack failures (which were common) and the subsequent misfires killed the cat within a few miles if you continued to drive on it. Depending on the age of your car your cat may be replaced under warrenty - but the only way to extend the life of the cat is to take it off the car. Our cats get HOT! Over 1600 F while just steady 65 mph cruising - and the "danger zone" for damage starts around 1750 F. I frequently see temps above 1750 F if I do any "spirited" driving/runs through 1st, 2nd, and 3rd. Personally, I'd love to be able to ditch my cat for a nice midpipe, but then I wouldn't be able to pass emissions testing. |

Within a few miles???? I drove nearly 1k on the new engine before I took it in! It only missed during idle though and didn't drive rough?

I'm guessing that since you don't have a CEL from the post-cat O2 sensor reading out of spec your misfires were less severe than those caused by a completely failed coil (as in the case of the miata's).

Check your battery as well... I changed mine recently and it made a huge difference
|
Rockauto.com has a full ignition for $230 if you want or need to stay OEM (like I do for warranty issues). It's a pain to install but certainly not out of the skill set of a shade tree mechanic.

Will more cranking amps help? Just curious... |
I am very new to this form I have a question my rx8 is misfiring not all the time for the most part the higher the rpm's the more it brakes up I've changed the MAF sensor I will admit I don't know to much about the rx8 motor
