03 with 106k miles

Symptoms: Starts with Check Engine Light Codes P0302 & P0303 and eventually gives all 4 cylinders. Was running fine until yesterday when the car would die at stops and at idle. It fires up just fine and I can continue on my way.

What I've checked so far: So I cleaned the IAC, put in a new PCV valve, cleaned the throttle body, made sure my air filter wasn't clogged. Then I decided to look at the compression. This is what I got

210
100
100 (Spark plug looked like it was running rich)
150

So am I F'ed, or is there a chance it could just need a valve adjustment? What does replacing bent valves usually run?

Thanks for any help and advice.

 

Leakdown? Retainer inspection? The compression numbers are going somewhere. If you've got no noticible bottom end noise, you might only need a little head work.

 

I don't have the compressor to do the leak down. I was only able to do the compression.

 

then find someone to leakdown test it becuase those numbers look awful.
