car starts but dont run rite, 91 integra, swapped out b18a1 for another less mile b18a1, the newer motor has a skunk2 intake manifold, other than that used all the same parts from original motor, i keep getn cel code 13, one long flash then three short flash's, it says its the baro sensor ( atmospheric pressure sensor) wtf is that. i read it was in the ecu, but the ecu was running two days ago. any ideas before i fork over cash for another ecu, i really cant afford it

 

Find another baro sensor and solder it into the ecu. Don't need to buy a new ecu.

 

u happen to know if they are the same in obd1? i got a p72 n a obd1 pr4, i cant find a baro sensor to replace it, honda wont sell me one cuz im not a dealer or a business
