So when I first installed my 3.0 after the rebuild it started,idled,and ran smooth othen than the code 52 that gave me issues. Well the code 52 is fixed now and got my lil bit of power back and gas milage back..but now latley when I start it up it starts up ruff and idles like it has a miss. After I run it for a bit I notice it runs a lot better(sound)still lacks what it should have in what lil bit of power these motors produce(also noticed if I run certain gas it runs different,mid grade seems to work the best).. question is,what should I be checckn for to solve these issues? I've got new plugs,wires,distributor,injectors...any feedbacck would be greatly appreciated..thanks

You're saying it runs and idles better once the engine is warm?

I have the same issue - it feels like misfire at cold start, but once it is warm, it idles just fine.

Any ideas?
