I have an 88 Iroc with the 305 TPI, and every once in a while when its hot out I turn off the car and get out and I smell the car running to lean. Thats what my dad said anyways. What can I do to change that? I have no mods on it, would a fuel pres. reg. help?

 

Hmmm....
You need to figure out what this means...

1. You could look at the plugs
2. You could have it smog tested
3. You could hit the local dyno

"It smells lean" is outside my experience
