Hi, I'm the original owner of a '93 Honda Del Sol. It's my all-time favorite car, and I'm a little worried about it lately. It revs high (about 2000+) when I first start it, and after it runs for a few minutes it idles at 500-700 and fluctuates. I always thought 1000 was the correct speed from start to finish without fluctuation. Also when I first start it it makes a strange noise (klump, klump, klump) which sound increases with speed as I increase speed. Then after a few minutes I no longer hear that sound. Hope I can get some answers after my 5 days and 2 posts. That's why I'm here.

 

Post up some pics!

What's the last major maintenance you've done to either the engine or transmission? SOHC or DOHC?

 

hey last time my car got a service was in June, was wanting to check it out before heading to a mechanic… yea I’ll post up a photo soon

 

Where's the del sol? That's a Honda Civic sedan.
