I took a reading with the vacuum gauge and it rapidly moves up n down from the 20 to 19 to 22ish at idle but it’s moving. I just swapped the motor and also when I go to start it it takes a bit before it starts but it does eventually but it seems to run rough the up and down idle i don’t kno if it injectors or there’s a leak I got the code p0315 it can’t relearn I didn’t swap the computer from the 05 the engine is a 04
thank u in advanced any help is appreciated
