Intake Manifold?? Running rough.
My car just started ideling rough, it will idel at around 600 rpms and then go to 1000 rpms and drop back down. Could the intake be cracked or a vacume leak? I have new plugs and new msd coil packs. So im thinking its the intake/ vacume leak. If so im going to buy the edelbrock victor efi intake with mmr fuel rails and new injectors. That should fix it. ... Hopefully.lol

MMR'S fuel rails fit my 03 block like crap. Very very poorely. Nightmare install with the engine on a stand. Also rails esp. And inj shouldnt cause a rough idle. Check idle air control. Tps. If u have an aftermarket throttle body ive had the blade stick closed at idle sometimes...just a touch of a turn... leared right up. Vac leak would also cause it. Just a few other options for you.
