hey guys

one of my spark plugs was shot, so i replaced it and everything was working fine for about 30 mins and then all of a sudden the engine light came on

now since i only changed the one spark plug would that matter???


oh i have a 95 accord with h22 swap, any good any solutions or reasons for this ??

 

Pull the 2 pin diagnostic connector from behind the glove box area. Cross the two pins with a wire or paper clip. Rotate the key to the ACC position. It will flash the diagnostic code of the CEL. A long blinking light is a "10" number. And a short flash is a "1" number.

Example:

Long-Long-Long-Short-Short=32.

Take that number and look under the FAQ section of here under the maintenance section. There is a write up for OBD-2 CEL codes. Under there is the OBD-1 code list. That will tell you what the problem is.

If you are stuck after that exactly what to do, let us know.
Hopefully can guide you in the right direction.

 

1) Did you get the correct plugs?
2) Did you install them correctly?

 

Changing 1 spark plug is being el cheapo man CHEAP!!! why don't you replace all 4 they're only $4 or less each.

There might be a reason to why only 1 spark plug fails.

 

Yeah, always good to do them all at once instead of leaving the other three at around 70% due while the other one is at 0% due and new.

 

is your motor vibrating alot more since the change? if one cylinders out youll see major vibration of the motor. or if you crossed to wires to the wrong cylinders will cause this as well. then youll get a misfire code, not sayin that what u have though.

 

I think it is fool/idiot proof coz the lengths of the lead are different

 

i got all 4 plugs
but i only had time to change one

 

You deserve a CEL for only changing 1 plug JK it could be sensing a difference in the pick up possibly...or did you gap it correctly? Is it firing properly? Maybe you have a faulty ignition wire on that cylinder. I would clean cap and rotor and replace all spark plugs and wires if possible. Oh yeah and like Tama said check the CEL code

 

Have you pull the code like Tammadrummer mentioned? It'll be easier if you start from there and you'll know what went wrong with it.

 

you'll be surprised, haha. but your right it is.

 

Yah because the plug wire became faulty only after he changed the plug??? Plug, wires, and u forgot your electrode greese, I bet them auto part stores love u, thats there #1 cure to everything.

*the only useful info here is to clean the cap and rotor only because thats useful in maintaining a healthy ignition system. and get the CEL checked out.

 

It is always best to change all sparkplugs at once. you might want to also check to make sure you didn't cross-thread when you put the sparkplug in. I dont know how much of a problem it can cause.

Finally you should diagnose your check engine light to make sure it's the sparkplug that's the cause.
