Nothing but problems after engine swap... Engine idals rough and misfires in most cylinders... Vac lines are new.. The car runs way better with the maf unplugged but the maf is new and just to make sure I exchanged it and the new new one is the same... Fuel line pressure is fine.. New fuel filter.. The car excellerates great but just idels like **** and the dash lights dim and brighten... Today while playing around with the radio I found that if I turn the key one turn the radio has no sound and the lights flicker tell I start it or turn it back... Could a short be causing all my problems or did I miss a damn ground when I did the swap... I got the grounds under the starter to the tranny and a ground by the pullies but are there anymore I forgot about... I've been rechecking everything all week and haven't got any codes and I have a spare ECM and that wasn't it... The only thing I haven't checked is air leaking in from the injector O rings but wouldn't that leak fuel?
