guess what....

P0303 Misfire Detected - Cylinders 1-10.

yeah..i guess misfires are popular these days! now...to find out where it is coming from. gonna replace all my spark plugs and wires soon...hope it fixes.

 

cylinders 1- 10?

 

dude he has a viper engine...

 

totally.

not. i just copy/pasted the code to the post.

 

then its the wrong code, u dont have 10 cylinders

 

even though my programmer said P0303.


it's still the wrong code, in the master code list.

 

So that means cylinder 1 aznd 10 are misfiring...

then everything is ok, cause you only have 2-9 right?



I think your mustang is trying to ask you for a V-10 swap in its own way.

 

maybe so.

 

Am pretty sure it should be cylinder 3 bcuz I had the same code not long ago turned out to be moisture in the ignition coil but you guy's don't have them. I would say spark plugs & wires like you said.

 

(P0303 Misfire Detected - Cylinders 1-10) this an universal code, thats why it reads 1-10, you will need to take the car to a mechanich to determine wich cylinder is misfiring!

 

No you don't...

 

try unplugging the cop see if it causes change in idle if not then you found which one is misfiring.

 

he does not have cops on his car, they came on the 99+ gts

what i would check to see... pull the number 8 boot and look to see if there is corrosion down it, on my mustang the heater hose above it leaked just a little and it trailed up and caused corrosion, resulting in a missfire... but yes, new wires and plugs should fix your problem...
