i have an 88 n/a s4 and I bought new plugs recently and car actually fired up first try and ran strong and after about 2 weeks the car will flood out. Then I push start it and it will fire up on one rotor and i have to hold it around 4k and after a couple seconds it will start running on 2 rotors and it will run fine untill I shut it off and try to start it again same thing happens every day i start it now any clues on why i went though 3 sets of plugs in about 3 months, maybe sticky seals or what?
thanx for any help,
steven

 

i guess nobody knows

 

what is your compression???

and the reason no one is replying, is because you have not provided enough info.

Like, When does it flood out?
or compression?
or why you are changing the plugs out? If they are in good condition (which they should be after only two weeks) then they just need to be dried out.

 

When I had flooding problems on my rebuild, the shop I got it from reccomended I install some cheap 94 nissan sentra plugs since they are less vulnerable to flooding/ fouling. I was skeptical but it worked, and I've been running them for about a week now.

I don't think this is a viable long term solution (although I don't know what exactly the dangers are). But they got my engine to start w/o having to do the de-flooding proceedure after every attempted crank. FYI a fuel cut off switch helps alot too.

 

ok i havent checked compression (scared). I try to start it every morning, it almost starts the first time but then i try it again and then it is flooded tell you the truth i thing my compression is low but im hoping it is somthing else but i guess the only way to tell is a compression test

 

today i took my plugs out and they were soaked so i turned my engine over and spew gas out and i took a suringe with 20w 50w in it and sqiurted it in the plug holes and dried plugs and put back in fired rite up ten minutes later. It also fires up every time now i just have to press the gas pedal a little bit. just did a little research on flooding and man does it help.

 

Now that you flooded your engine multiple times, your oil is shot.
Feel free to change your oil and filter to remove that gas soaked motor oil.

Check your oil injection or just run a little supplemental premix to see if it helps. A bottle or 2 of FI cleaners might help with clogged or pour injector spray. Try a bottle of Regane, Redline, or Techron Concentrate at your next several fillups.

I wouldn't use Sentra spark plugs. That same ground electrode that help prevent flooding prevents the fuel from contacting the spark as efficiently as possible. And, I wouldn't use a 'normal' plug without testing that plug in a disassembled engine. That apex seal might come in contact with the ground electrode which would........

Another method to move the spark closer to the fuel is not to run plug washers. But, you want to test the stock plugs on your housing for that same seal clearance. And, you can only do that during a rebuild.
