The emissions sticker in the front of my son's 89 firebird is gone (painted over it looks like). It's a L03 TBI car with automatic, and air conditioning. Can someone tell me what the base timing is supposed to be?

Thanks,

John.

 

Should be 0 deg. around 500 rpm or so with the est connector disconnected.

 

 

Yup. I did a search, but found lots of different messages. Most indicated it should be 0, but just wanted to make sure.

Thanks.

John.

 

0&#176 is whats recommended but around several degrees more wont hurt anything since the stock timing tables kinda suck
