So I just got done putting a 22re block into my 84 Toyota pickup. I had the old 22r block running great with no issues until the engine blew up. Now with the 89 block installed it's having a rough idle and an issue. If I screw the idle screw all the way down it still runs. I’ve checked for air leaks multiple times and can't find any. I've unhooked the cold start, new TPS, check the air tube, new gaskets on everything and I cannot for the life of me fine it. Any help is wanted as I'm sure there's something over looked. And yes my truck is EFI with no emissions stuff left on it.
