RE: 95 Blazer HELP BIG PROBLEM
yeah i figured with my luck it cant be easy lol
i just replaced the plugs not too long ago but not the wires so i guess i will pick up new plugs anyway as well as new wires, cap, and rotor and see if that gets it done
the plugs didnt really look bad at all when i did compression testing they were just a little tan like a cardboard brown color and didnt smell weird but i know that they can sometimes fail without looking bad so i can give that a shot and see what happens

To give you a closer answer, you really need to get the codes read.

I agree and I will get that done asap and let you guys know
ok i did have one last question, if the cat. converter is plugged would it make it feel like it has a miss?

Allrighty guys just to give you an update, I changed the oil and it was fine and the antifreeze has stayed at the same level so hopefully no gaskets are bad
I did a compression test and all is good there
Today I changed the plugs, wires, cap, and rotor and it is running FANTASTIC, actually its running better than it has in the 6 months or so that we have owned it. The cap had decent wear but the rotor was destroyed with really no good surface for contact.
the check engine light is still on but i only drove it for about 10 minutes after the new plugs etc etc etc so i hope it goes off in the next couple runs or i will have to have the codes pulled.
I hope that the catalytic converter or sensors were not damaged due to faulty spark or not full combustion from the same issue but if they were i guess ill deal with that tooo
I wanted to thank you guys for all of your tips and you are truly a help in the face of a disaster
Thank you sooooooooooooooooooo much

A blinking CEL is a sign of a misfire. The CEL should not be illuminated if you are low on antifreeze unless you are low enough to overheat the motor.
If you are loosing antifreeze fast enough that checking it once a day can't keep you ahead of it, you have a serious problem and should not be driving the truck. If you cannot find any exterior signs of leakage, then it is leaking internally, either through a failed lower intake manifold gasket (where it is leaking into the intake port, being sucked into the cylinder and sent out the exhaust) or through a failed head gasket.
I would start by pulling the plugs and looking for signs of coolant on them. Then run a compression check on each cylinder. If you find one that is significantly lower than the others and this same cylinder also showed signs of coolant on the plug, then you have a head gasket failure on your hands.

i was told that if your exhaust smells weird or burns your lungs ( it was described to me as a pepper type smell ) then you have antifreeze in your cylinders and it is steaming out your exhaust but also the guys on here told me to check compression and see if the compression is the same on all cylinders so i would try that. I found the best way for me to get to my plugs was to jack up the front of the car and remove the wheel, the i just hold up that rubber inner finder and there they are.
May not work best for you but it worked good for me
also i forgot to add that if you dont have a compression tester you can borrow one from oreilly's or auto zone with a minimum deposit which you get back when you return it
