Ok I'm still new somewhat to the site and now have serious problems. I had a shop replace my engine with a JDM engine to drive around until I have a garage where i can build a new one from top to bottom. They have seriously screwed up my car. It's still at the shop and they do not know what to do and asked if i knew anything. So here it is. When you start it up it revs up to 2000 rpms and stays there. It has a little stumble as its idling there. Then when you hit the gas, it just about dies but recovers. They haven't drove because of that so I don't know what else could be wrong. I'm sure it's vacuum line problems for one because they said they had problems with that. What exactly could be wrong other than that? I know the BVSV vacuum lines going into the t-housing have been broke off. Could that make most of the problem? Thanks for any help. I am totally getting ticked off with them. They have had it for 4 weeks now and its driving me crazy. I will never let anyone touch it again after this disaster.
