P0622 & P1294 Check engine lights

so i've got a 98 jeep wrangler 2.5L and i just replaced my exhaust manifold since it was cracked. prior to this everything was running fine with no CELs, but after i got these two CEL codes P0622 and P1294. Can anyone help me here? i've searched but havent found anything in particular related to P0622

I had p0622 before on a dakota (all the same codes as jeep) and it turned out to be a short in the ground. If thats not it, I can tell you it has something to do with voltage for sure. I'm sorry I can't help more I'm sure someone will but I would start by checking your battery voltage.

This site has a list of all Jeep codes. You might need to look under the Generic code list as well.

yea i've checked them all. just as an updater i've narrowed down one of the codes. i bought some carburetor spray and started spraying around the intake manifold and what do you know? theres a huge leak. the cars idle drops whenever i spray aroudn there. i tightened it down as much as possible but still leaks. just replaced the gasket last week i guess it didnt seal properly. can anyone recommend me a good gasket to replace it with?
