I know! I took it out for a test drive after work and man! Did it drive so much better! Idled and it actually felt more responsive. I got it up to about 110 on the interstate and the car felt great!
This is what I'm going to do Every year...
1. New Plugs
2. New Coils
3. New Wires
4. Clean air filter
5. Clean TB
Its about $300 maintenance cost but I think its worth it if it give me worry free drive
