P1272 P0266

My buddies 97 is running rough. Now I know I should be in the OBS section. . . nothing wrong with that section but you guys are family

Anyway, it sounds like its missing a cylinder. . . or most of one. I pulled these two codes after a contribution test and a buzz test. P1272 states Cylinder #2 High to Low side open. English? During the buzz test the Number two injector is quite noticeably quieter. Contribution test gives the P0266 which states Cylinder 2 injector circuit contribution/balance fault.
Whats everybody thinkin? I'm thinking pull the valve cover and make sure the connection is good. . . and if it is then I'm thinking we just have a poor injector. However, I'm worried it could be in the IDM or somewhere else. Let me know what you guys think. Thanks guys! Oh and not to get all teary or nothing. . but I love you guys!

Also I'm getting a P0470 for exhaust pressure sensor. At idle the sensor is reading almost 53 PSI. i know thats not right.

id say pull those VC off and check it out first before you go nuts. than change the ebps cause thats what gives you the reading of 53psi, did you ever check you tube if its cloged? mine was solid like rock inside.

i know cold wether does not help for sure, fingers dont want to work like they should. But i would do it as soon as you guys can cause that cylinder not working properly can only cause more problems down the road.
