"would have pics but dont know how to upload yet"

 

Welcome to YT! It is possible for it to be a dirty injector. Check your connector to make sure it is getting contact. Is it a constant miss, or occ. You need a photobucket account (or one similar) to post pics.

 

thanks and yes its a constant misfire

 

A constant miss is easier to find...

How does that plug look compared to the others?

How do you know you have spark from that wire and plug?

Did you get a P0306 and a P0300 code?

Injectors are very very rare on the 5VZ to go bad.....

 

the plug is clean even traded it with another i took the wire off and checked for spark. its getting plenty lol. im gettin p0306.

 

Well,then it can either be one of two things..compression/fuel.

You can swap the injectors to see if the miss will move,or put one in there.

Another trick is spraying some carb cleaner into a vacuum hose and seeing if the miss gets better..if it starts to smooth out you have a fuel problem...not too much to foul out the plugs...but hey plugs are cheap.

Compression test..low on just one cylinder is rare,but I guess it could happen.

By the way, what did that old plug out of that cylinder look like? This could point you in the right direction as well....

Good luck.
