I just installed a new set of ID 1000cc injectors. I have gotten them to start and idle great at high 14s low 15s AFR when the engine is cold. If I try to restart the engine after it has already come up to temperature it will have a very low surging idle between 300rpm and 800rpm and the wideband has the AFRs at high 18s and higher. After a minute or so it will slowly start to catch idle and settle down. What should I be looking at?

 

Try playing with your fuel versus temperature compensation tables.

 

Thanks for the response!
I am assuing you are referring to water temperature? Water temp correction setting at low engine load are...168*/4% - 177*/0% - 302*/0%. Should I increase the last two to about 5%?
