Why did you put the injector cleaner in in the first place?
Without knowing anything about the car, I'd say an injector is stuck open or something like that; fuel related.
It could very well be that the cleaner broke something loose that is preventing an injector from closing. That will dump too much fuel. It may be enough the puddle in the intake manifold. During the overlap period of the cams they need to breath back into the intake, if fuel is blocking the path it can backfire; the overlap air is warm.
If this is the case, pull the fuel pump fuse and try to clear any extra fuel this way. It isn't the safest method but so long at your careful it works.
Once the car dies on it's own, try starting it a few more times just to be sure.
Then pull the connectors on the injectors, put the fuel pump fuse back and try to start the car. If it starts or makes a better attempt than previously, odds are an injector is stuck.
My best advice here is the have a shop flush the lines and replace the fuel filter. Then replace all the injectors with known good ones.

|Bananas HD||I had some STP fuel system cleaner that I had and decided to put some in, and i had just under half tank. then i drove it to get a bite to eat and when i was leaving it started sputtering out and didn't want to stay running (its a stick shift so i was able to) and then it stalled out and i couldn't get it started to get home. it sounded like it was missing and was shaking pretty bad, the RPMs went down so far it went like all the way down on the tach, then a friend towed me to the gas station because we figured i put a little too much in and filled it up to maybe dilute the injector cleaner and worked enough to get it home but when i got it home it would not stay running until the RPMs got up. then it started backfiring from the airbox and smoking just a little from the exhaust. then we called it a day.|

Seems like you didn't read any of the responses.
The zetec does not have valve or valve seat issues. So there should be no need for pictures or anything related.
You haven't described your problem in any way other than bad information you've been given from a friend. We don't know what's going on so we can't offer advice on anything really.
What's the problem with the car?

well like i said I'm new to the focus scene and thats why I'm here, to be honest, i only joined because I needed help with this situation. I don't have too much interest in focuses and just want to fix it.
It seems like you didn't read the 2nd post I made...

|calebstubstad||alright, being the owner of a lx, would it be smart just to put money down and replace my valve seat before anything happens? i'm at 122k odd miles, right around where the problem starts to happen and i dont want my engine destroyed by this. or is it smarter just to let it happen? how much is the repair anyways?|

Please don't take this personal.
If you are not able to determine valve condition BEFORE you pull the head then you are not competent enough to yank the head and get it reinstalled correctly.
I say it as a friend. Save yourself what could be massive wasted effort.
A simple compression check would do much to help you make a decision.
Valveseats in zetecs cause virtually no trouble at all.
