I took one plug to see if its bad or no, doesnt look bad, right?

 

It looks way rich did you just start and let it idle for a few minutes? Please give us the history on your car, miles, service, parts replaced, type of driving it gets?

 

04 RX8, 91k miles, been sitting, has a hard time re-starting , now its clearing up and able to e-start back you. Dont know much on history

 

It might need a new air filter. So I'm not sure if you meant it is running fine now? Where you said "able to e-start back you" please explain.

 

its gotta a pretty clean K&N filter. It used to NOT be able to re-start right away after turning it off, now its getting better, i believe it was flooded

 

I got you now. You might get some benefit from a good de-carbon cleaning. Also do you have the new style starter motor.

 

not sure, how would I go about to found out?

 

so what fixes the hard start?

 

if its never been done before, im sure it will help alot, and i'm talking about seafoaming you're car.

theres a diy somewhere around here and its really easy to do. you might need a friend though. i put a wooden block on the gas pedal when no one was around.

you can find seafoam at walmart or any auto store (autozone, oreillys)

 

will seafoam clean up the plugs? would I still need new plugs?

 

put new plugs and coils in the thing

 

It will clean them up some.....but spark plugs wear out and you don't want it to break off and scar up your engine. Replace them, coils and wires it's called preventive maintenance.

 

Get a whole new set of plugs, see how that goes. Cause if 1 looks like that, most likly their all burnt and fouled out looking.

 

better safe than sorry, good luck with everything!

 

thanks guys, installing new plugs next week

 

My 8 has always taken a few cranks to startup (up to 7 or 8 sometimes), even after installing a new yellow top battery. I haven't yet done the decarb or swapped the coils, plugs, and wires, but a couple of days ago, I filled up with half a tank of premium (which I always run), and added 3/4 a can of seafoam w/o premix. I started it up and let it idle - it was smoking out the tailpipes and dripping carbon cleaned from the tailpipe even, for a few minutes. I ran that for 1/4 tank, then ran the last 1/4 tank with 4 oz. of MMO added to help protect and also clean. Then at next fillup I did 8 oz. Idemitsu and 4oz MMO to get the protection back in action. It now starts on the first crank, and it also has higher torque response at high rpms.

 

did you just stick the seafoam into the tank of gas?

 

sorry guys, but what does the seafoam supposed to do??

 

i thought you dump the whole seafoam in a 1/2 tank of gas, it has to be a full tank?

 

That is the simplest way(best results half or quarter tank) but the best is add it directly to the engine threw the manifold. I've done both....
