OK so i am driving to my dads house to go wash my car and also reconect my secondary O2 because i just put on a new header and got my exhaust done.as i am driving i noticed the CEL starts blinking , then the car starts to feel slugish and sounds like its runing on 2 cylinders. keep in mind that the CEL was alredy on because the secondary O2 was not pluged in.
Any ideas on whats wrong with my car

 

loose plug wire, or moisture in dizzy cap

 

good point i will check that out

 

its probably that secondary o2 you have to reconnect..

 

you might want to check your spark plugs too. someone had the same problem and they also compared it to sounding like a subaru wrx. they sad when they checked it, that it was just a bad spark plug.

 

haha yea one of ur wires is loose, probably on the destributer cap.


happend to me once, i love how it sounds lmao.

 

also..jump the CEL

 

i had that happened to me once and the headgasket was bad and was leaking water into the cylinders

 

checked plugwires all look good and on tight, dizzy looks ok no moisture.
i will have to wait to check spark plugs until i get a deep socket. I also drove with the secondary o2 unpluged for three days no problem,

 

jump the CEL and tell us what it is..maybe you'll find out what your problem is.

 

ok tomorrow i will do it and let you know

 

So i jumed it and this is what i got


74 random misfire cylinder 4

</TD></TR></TABLE>there you go, a problem in cylinder 4, check ur plugs wires and maybe dizzy/ cap and rotor, if all is good then its ur head gasket

 

if it is my head gasket wouldn't be smoking like a champ

 

I've seen some seriously WARPED heads causing coolant consumption and thusly misfires, but there was no real smoke to speak of. at least nowhere near what you'd expect for a blown headgasket.

 

ok i am waiting to get a ride to the auto parts store so i can buy new spark plugs and get a deep socket to take them out i hope its just a bad plug

 

Secondary O2 only monitors the cat, it has nothing to do with the engine misfiring.

Since you have a misfire code for cylinder 4, make sure you check every part of the circuit inline with that cylinder, starting with the contact points in the cap, to the plug wire connection at the cap. Perform a resistance check of the number 4 wire, and see if its shot. 25K (25,000 Ohms) indicates a shot wire @ 70 degrees. Check the plug hole ,and make sure no fluids got down there. Then check the plug itself, and make sure gap is correct, and the plug is not broken.

x2

There are times where exhaust will be forced into the coolant due to compression, as well as air/fuel, but not enough pressure in the cooling system to force coolant in the chamber.

 

Checked plugs they looked like they could be replaced so i did car still sounds like s suby

 

motor has about a 100,000 miles on it

 

did u change the wires yet? check for fuel too cause u may not be getting fuel to cylinder 4.

 

I have msd distribtor and wires that are about 15,000 miles old

 

probably water / moisture somewhere

I had that problem before too
Sounds lik e a wrx but much slower
