I just read the VG thread and wanted to know the same thing he did. When my car is warm is runs like crap. 1st gear used to take off at about 3k, now it is more like 3800. Even when it does take off, it just isn't the same. The overall performance of the car once it hits the warm line for about three mins is really pathetic.

In what order would you start doing things? Can you give aprox prices for the parts as well as difficulty of doing stuff on my own? Thanks.

BTW: Replaced:
Spark Plugs
Fuel Filter
Cleaned Air Filter
Replaced bad #2 injector

 

1) Red coolant temp sensor, clean the connector
2) 02 sensor
3) Knock sensor(probably this)
