Is the check engine light on?

 

No check engine light on at all

 

I did check no light on at all

 

Try pulling codes and see if any come up.
You might also want to try resetting the computer.

 

I did check and their was a code 121 and reset discon the battery for about 15 min then sarted the car and checked no codes. Now I still have like a missing in the morning when it is cold out.

 

Might be a small vaccum leak or a leaky injector.
Does it smell bad when cold?

 

Hello I did check all the injectors and found that the one close to the firewall was lose so now what do I need to do to fix that ? And could that be the problem? Also could you give me a Idea on the way and steps to fix this ? It woudl be very helpful

 

You need to replace the injector O-rings.[/align]There is 2 screws that hold the injector rail into the intake manifold.[/align]You should be able to just remove the 2 screws and pull the injector rail back far enough to get the injectors out to replace the o-rings.[/align][/align]When going back in with the injectors spray a little silicon or something like that on the o-rings before installing this way it won't tear the new o-ring.[/align]
