The last time my 8 flooded was about 3 months ago. Today I drove 20 minutes to school, got there and turned it off around 7 am. At 2 pm when I got out to go home, it was flooded again. Tried for awhile and when trough the procedures and even ripped out the fuel chip like I did last time.
While I was waiting for the tow truck I figured I would jack it up real quick and take out the plugs since I had an hour to wait and I always keep my tools in the trunk. I changed my plugs 2 months ago and both of my trailing plugs were black and brown already and my leadings with just a little brown. But I’m not sure why my trailing plugs are shot already. Can any one help me out with this possibly? I had an extra set of plugs in my tool kit so I put some new ones in right away but no help. I’m not worried about the flood, I’ll just let it sit and I will get it running in a day or two. I called Mazda and they want $150 just to look at the plugs I already pulled out wtf

 

Please give us the history on your car, year MT/AT,miles etc... The service it's had parts replaced. Did you do all four coils , wires? Type of driving it gets(long commutes, short trip), fuel used(reg or prem). Just any thing that you can add. Done any decarbon cleaning? This will help improve the compression. When you say flooded do you mean it just keeps turning over but never starts up? Do you have the upgraded battery and starter motor?

 

Were any of the plugs wet or greasy looking? and ditto to the above question.

 

I bought the car last may with 48000 miles and I just hit. 50000 miles last saturday. I put premium gas in ir and its driven about 30 miles a day. Changed the spark plugs at 49500, lately it feels like a little loss of power.

 

And I get the oil changed at the dealer, got a neew battery two months ago and I am planning on doing the ignition wires this week

 

If the plugs were dry then it didn't flood. Have you decarbed/seafoamed? Does the starter sound strong while turning or is it just going through the motions?

 

Starter sounds pretty strong, but then again while I'm tryin to get it started I have my jump box hooked to the battery so it doesn't lose to much power. I have never done the seafoam.

 

Bottom plugs were black and brown, they were pretty foul for only being two months old. Top plugs were in pretty good shape just a little brown. I'm thinking maybe running a little rich. Could it be the MAF sensor? Paybe not reading properly and tell the comp to add too much fuel?

 

What year is your car? If it's a 04' or 05' it might need the updated starter motor. Get the numbers of the label on the starter. Can we see a pic of your plugs? You might need new coils. Most replace plugs,coils,wires together the first time(about $250-300) it takes about an hour. The MAF sensor is easy to clean. Most maintenance can be found in the DIY section.

 

Its an 05 and its not flooded but it still doesnt want to start. I had the wheel off and pulled out the plugs and just left the holes open for a good hour, pulled the fuel relay and cranked for a couple seconds because if it was flooded the fuel should some out of the spark plugs holes but nope none came out

 

 

So i went out today to try again, and see what else i could do and it started right up first try. weird..

 

Glad it's running. Your pic is not working....

 

sorry about the pic.. yesterday i was taking it to the dealer to get checked out and i needed to get gas to get there so i stoped at sonoco and put 10 bucks in it. the car started and as i was rolling away it stalled, it wouldnt start for 10 min. i got it to the dealer, they called me today saying the have been taking it in and out of the shop and its starting for them everytime, and until it wont start they dont know whats wrong with it. i asked them to do a compression test which they didnt do today so tomorrow i will call again and tell them to do it. i was doing some research and came across this thread https://www.rx8club.com/series-i-trouble-shooting-95/warm-start-trouble-please-help-192345/page2/ turns out im not the only one having trouble
