ok so about a month ago i took off my intake mani to plug up my vac lines because the old plugs where really old and to change my pcv valve. As i was scraping off the old gasket i kind of scratched it while scraping it off. ive read that it can really mess your idle up if you have a leak, but how would know? Also while i was putting the pcv valve in i didnt know how far to screw it in and it kind of made a crack noise. I didnt have time to really get another so i put everything back together and now it idles like crap. Do you think it could be because of me scratching the intake mani and the pcv problem?

I WOULD SAY THE PCV, BECAUSE THE GASKETS ARE PRETTY THICK AND DID YOU USE GASKET SEALANT. NEVER DO RUSH JOBS IF YOU NEED IT DONE FAST TAKE IT TO THE SHOP...UNLESS YOU PUT A DEEP SCRATH MARK ON THE MANIFOLD
