Go to realoem.com to find what the part numbers you need and order through pelican. A cracked intake boot will give you a bumpy idle. It's just a good idea to make sure all the hoses are crack-free.
NGK plugs all the way. OEM is perfect. OEM wires, I've heard aftermarket wires have a tendency to be shltty.
Other ideas. Seafoam the car(gas,oil,and get some though the brake booster(youtube will show)), clean off the throttle plate, clean the ICV. These will cost about $20 and will most likely cure a majority of the idle and acceleration issues. Just as a note an vacuum leaks, they are usually the main cause of any blips in the idle or rough engine speed at low rpm's.
You canít spend all your time worrying about where your next Twinkie is going to come from, so follow rule #32 and Enjoy The Little Things.
