spark plug help

[fugees8]

i just changed my spark plugs and now my jeep is running kind of rough and my check engine light is on?

[JDPascal]

So have you double checked the plug wires with the firing order??? 153624

#1 is at the bottom of the distributer cap and 6 is at the top. distributer rotation is clockwise.

What kind of plugs did you use???

Were the plug wires difficult to remove that one was damaged??

just brainstorming here......

Did you gap the plugs correctly?

[jsmiddleton4]

What year? Did you pull something loose for the wire harness?

[fugees8]

all wires are correct, i used the plug selection manual for my 96 cherokee at walmart and was assuming they were correctly gapped

[fugees8]

the check engine light also blinks when i accelerate hard

[xj31]

never assume that they are gapped.all it takes is for the box to be dropped 1 time and it can bend the side electrode.also are you sure you didnt crack one of the plugs putting them in?Did you use an actual spark plug socket or just a deep socket?a spark plug socket has a rubber insert to protect the porcelain which is pretty fragile.also a blinking check engine light means possible catalyst damage so if you keep driving like that you can melt the converter

Like xj31 says, never assume the gaps are correct. Double check them. Did you pull on the wire or the boot when you removed them? Are you sure you have the wires pushed on all the way?

Try pulling the codes to see what's causing your check engine light to flash.
