1.) Do a full tuneup.
2.) Get your timing set to zero with the black and brown timing wire disconnected from the PCM under the glove box. It will be under the edge of the carpet.
Don't start replacing sensors unless if you have a check engine light on. Then you can get the codes adn pin point the problem.
