well i got the complete drive train from the pinks car in my capri today was the first drive in the car runs real strong for a few miles than starts to run like its firing on 4 cylinders cuts in and out.if you shut the car off and restart it it runs good for about a minute and looses power again. any help would be appreciated thanks:headscrat

should have put a sbf in it.........on a serious note it might be a wiring issue or maybe an over heating issue or both
 
lol ya it is a wiring or computer related issue i think i checked all the plugs and wires nothing was loose just riuned my day thats for sure was gonna try and make it 2 milan on saturday
 
yeah like i said, it sounds like something is being exposed to too much heat and it runs like crap, then when it cools it runs good again......maybe the ignition box?
 
My Camaro ran like that, it would throw a CEL for o2's? Or it could be a coil pack going bad?

i don't think it has 02's or a maf

it had a maf, no o2's though


the PCM is under the hood from the factory on LS1 cars, so unlikely to be an issue, unless its super close to the exhaust



it loosing any coolant?


check plugs?


when its acting up, see what cylinders are missing, safest way is probably unplugging the injectors one at a time

then, once you know which cylinders, you need to check for spark

no its not smoking so i think the coolant is ok,i put the pcm in the same location as the pinks car and i put an exhaust on the car,car isnt over heating and like i said it runs good after you shut it off and turn it right back on.im gonna do like you said and check the injectors in the morning. thanks

kinda what i was thinkin ,but im new to the ls1 motors so i figured ide ask first since there are alot of guys on here that have had there hands in on the build
 
You should search google or ls1tech.com - ls1.com - camaroz28.com
Or post this on either of the 3.
 
Pull the fuel rail and check for debris in the injector screens. With the problems the fuel hoses had its totally beliveable that the hoses may have broken down and clogged up the injectors on the passenger side of the rial where the trash always accumulates.
