I am cleaning my cold air intake and replacing the filter right now because it was filty from the previous owner. Ive noticed that the car has a generaly rough idle and has a bad surge at start up. I need to clean the maf (spelling?) sensor and the throttle body. Does anyone have any tips? Ive had a 2000 Grand prix and I just sprayed the throttle body cleaner inside and let it drain a few times. But I would like to do it proper with this car. Any tips? Thanks!

Im also about to replace the spark plugs with some new ac delcos, but ive got a haynes manual for that

 

dood dont get delco's get ngk's step 1 colder plugs. thats all im saying
