Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Misfire like no other



The one Reptile was talking about actually had the supercharger gasket hanging up on the coolant o-rings that run thru it and it was sucking coolant from there. You might look it over really good after you get the supercharger off and you may not need to go any further if yours is getting sucked in there also.
 
It's a shame you're so far out there, or I'd offer to help.

Now, just to say something else. It is most likely NOT a head gasket, and I'll tell ya why. If it were one, the cylinder pressure would eventually blow the top off of your overflow bottle. The manifold pulls vacuum, which is probably why your engine is only sucking coolant. But, once you get the manifold off it should be pretty clear where the coolant is coming in at. It always leaves a trace.

To that point, I once read an old school troubleshooting technique where if you have a bad/blown head gasket you let the car sit over night, then go out and start it up and grap the upper radiator hose. If the head gasket is bad, that hose will pressurize within seconds of the engine being started.
 
ok well i checked for coolant in the cyl. no coolant on plugs. right now im more worried about this miss fire the coolants not in the oil so not to worried. well this miss fire seems to be bad plugs. the bad thing is the spark is not going through the spak plug instead it sparks off to the insulator. spak plug or wire. (the wire is a cheep set i bought last summer.

Inaccurate. Different plugs for different performance gains.

Longevity go with platinum or iridium. If you want a good plug but don't mind changing them once a year, get coppers like the run of the mill 104's.
 


i really dont mind changing them but the last 2 sets or plugs have barely lasted me 6 months. first set was NGK second was AC delco platinum. i just want a plug that doesnt cost 50 bucks a set.
 
Spiro pro is about the best you can get for a daily driver. They're insulated pretty well so that you won't get that interference in the radio.
 


have you ever seen this and do you know what might cause this.
