Hi, This is my first post. I have a 2001 s2k that sometimes floods cold. Will run very rough for about 20 seconds then clear out or not start at all. When it won't start i have to remove and dry plugs. All sensors in spec, missfire codes present. I don't know if too much fuel is introduced or timing issue. Problem has become more frequent since turbo install ( larger injectors? ) Pulling my hair out. Please help

 

Simple you need a tune.

 

Thanks for the reply. By a "Tune" do you mean a fuel mapping of the ecm?

 

What are you using to adjust the ECU after installing larger injectors? Without proper engine management you will have a blown motor in a very short time.

I am using a Greddy e-manage blue system.

 

Ok, more info. This morning cranked for maybe 8 revolutions, no start. Pulled plugs and found coolant on three of them. Seems odd to have a head gasket leaking on three cylinders. Has anyone seen another source for coolant in the cylinder?

 

Ah, you have coolant on the plugs. I was presuming it was wet with gas from being too rich on cold starts, in which case you could "fix" through software/tuning. But coolant is an indication of an entirely different issue.

 

Yup, thats what I thought at first. Previous times I pulled plugs was after extended cranking so all I saw was the gas. Looks like a head Gasket or worse. The only confusing thing is that there is coolant in more than one cylinder, and only a few drops.

 

could it possibly be condensation and not coolant? does it smoke/steam out the exhaust after it warms up when not cold out, or does the coolant levels drop without signs of a leak?
