I am using the original ecu that was on the car. I have checked all earths and they are all fine. What do u mean by common power? And when I delete codes it's still the same it fires up but does almost instantly with the same error codeshare

I'm being told by mechanic it could be the ecu the ignition module inside. This is because he has checked all plugs and sensors

I have had my engine replaced due to it drinking too much oil. The engine I used was from a 1998 auto and gone in to 2004 manual. Cambelt was replaced before fitting. The engine was fitted and started fine warmed it up and everything is fine Yesterday I fitted bumpers and lights back up and was revving it all of a sudden revs dropped and engine cut out. Error codes I am getting are p1305,1315,1320 and 1325. Any ideas or info would be of great help
