ok i have a ground wire on my catylic converter i took the bolt off so what ever it is its not grounded anymore my first question is what is that ground to? and does it matter if it is grounded?

My next question is i got the codes 0102(MAF),1102(TCM COM LINE), and 0504 (A/T CU) What could these come from ?

Im thinking its an electrical problem with the tranny or Maybe the Tcm but i dont see y it would just go bad .

Thoughts?

MAF - might be an intake leak
AT - maybe that ground you removed caused the codes?

The ground is useless, don't worry about it.

The AT codes could be from a damaged harness or bad TCM.

MAF code is most likely just the MAF.

Have you reset the codes to see if any came back?

Well i was driving along when all of a sudden the revs jump way up and then the car kicked forward it kept doing it over and over again.It mainly does it when im going up hill and i have to keep the throttle real low to drive it and the rev stay high the whole time .

Sounds like a failing MAF. and that cat ground is silly

Either the tranny is done, or the TCM is failing.
Do check all the electrical connections to the tranny 1st.

Sounds like a MAF or TPS issue.

so dude, why bother posting as it seems your not LISTENING to what they're telling you. dont just throw new parts on the car, that aint gonna solve squat. reset the codes and see what it does, did you even try cleaning the maf or making sure everythings connected. cant help you if you do things back asswards.
