so i did a mpfi conversion and swapped in a ls. throwing a code for the IACV, and i feel its because of the vacuum setup. i checked for vacuum diagrams, but the integras have an extra solenoid in the engine bay than the dpfi ones, and the wiring conversion doesnt mention anything about wiring in the new solenoid. is there a vacuum diagram for mpfi conversion? or can someone whos made the conversion code free draw me up a diagram?

 

could be wrong but the iacv doesnt use vacuum.. only has two coolant lines and a plug.

 

https://honda-tech.com/zerothread/1936854 second picture should help a bit.

 

yeah it doesnt have a vac line but i heard bad vac routing could cause it to throw a code or something? plus i know my vac lines are wrong lol. thanks for the link, whenever i search for vac diagrams i cant find anything useful

 

iacv doesnt have a vacuum line at all. unless b18s have a vacuum for the iacv i think your wrong. my a6 iacv only has two coolant lines and a plug.
