One day after a cold start my 2007 rx with 140 on the dash decided to start driving rough with an engine light. I stop at Autozone to get the codes 304 and 302 I take it to my mechanic and they say that cylinder 4 is giving no compression and that it is “dead” and that I should just get a new engine…? Should I risk more on diagnosing a cheaper fix? It was just driving good

 

Here you can DIY it, months of fun, save your car for 2k or so, plus you will have some cool new jacks and tools: https://www.clublexus.com/forums/rx-...ve-spring.html
