Maybe its time to try the IMG. Rule that out. Its a cheap easy garage repair. The plastic and metal expand and contract differently, so the chance for a vacuum leak is high.

Heat will work if u dont have torches try mapp gas fro the hardware store or impact gun but probably can't straight shot. But you will have to get a o2 thread chaser.

What was suggested in the beginning..manifold gasket..the computer is probably trying to compensate for the extra air and dumping fuel. You can rent fuel pressure test kits for free. This will tell you if you have a fuel pump or regulator problem. It wouod even show a leakimg injector. You may have a fuel leak. Cylinder 7 and 8 aren't on the same bank. What they do have in common is they both on either side at the back of the intake.

All I want to know is how in the hell do you improperly install a sparkplug?!

i think @01ssreda4 mightve been right initially. yesterday i got my baby to the shop, they used a torch and got the damn thing out of there. it was fouled and worn out. they put in the new one with proper antiseize on it and so far so good. if the same issues come up again can you add something to the tank to solve the Intake manifold gasket leak? ive seen some products at autozone. is it okay for a temp fix then replace the gasket? so far so good but if the isues come up again i will check this next.

and @bottomline2000 i dont know how he left that shit loose. the mechanic to took it to for diagnostic called me over and pointed to the sparkplug and told me to reach down i guess to prove he didnt do it but i drove in with it like that. its a lesson learned. not going back to that place and will stick with the new spot.
