ok. i see most have given up on me

since the majority of answers are in my other post...

i guess plain and simple:
1) why do my lights dim on acceleration?
2) can a new IMRC be cooked due to a severe overheat?
3) Do i bite the bullet and change the cats.. or could it be anything else?
thats the distilled version of my post, the rest is just alot of venting!
