Computer is able to display codes...i believe it my idle speed sensor.or my air intake temp sensor i replaced 02 sensor cuz it was faulty map and throttle positon sensor are working withing voltage range i changed plugs wires cap rotor (button) coil and comp due to burnt circuits so theres nothing left to check change or replace ... Oh and i have sufficiant fuel pressure

I only have 2.5 volts to my intake air temp sensor ... Anyone one know what it supposed to be and should the other wire have any readings ? Im runnning outta time money and patience

Did you check and possibly replace fuel filter? Also might want to take off the air intake hose and spray cleaner into throttle body intake port?
