so i have a 1989 crx with a obd0 LS,i was turbo for a while,it had a missing link and fmu.but this weekend i went back to stock.SO when it came to pluging in the map it would not hold idle and it wont start unless i give it gas.im open to any suggestion.thanks

 

I assume you removed the missg link (probably wouldn't matter if it was sitll on).
Are you running a chipped ECU with a turbo program on it?

 

make sure the missing link is removed but it shouldnt matter at idle, even if he did have a turbo program in the ecu the vacuum portion of the map should be almost stock and it should still idle and run fine. but if it had a missing link and fmu I doubt it had any ecu tuning, did it have larger injectors and the stock ones were swapped back in, try stock injectors . it should run fine if just the turbo and associated hardware was removed, was the base timing messed with check the timing as well

 

yeah its all stock.when the map is pluged in to the vacume i got to give it gas to start,then it will die out,when its not pluged it starts right up
