Ok so we picked up a free 93 lude, h22a, and it has been a mess. Im down to my last code, 10 iat. And its been no go. Running p13 ecu, 13.3 volts to the iat, and nothing out the ecu. Tried to run off the ecu and that dont work. Any ideas on what else I should look for? Ecu looks good on the inside.
