Hello everyone,

I have just about finished a '91 4.3 swap into my toyota and this thread has helped me out a whole lot.

At the moment I am having a few issues. When I start the truck it runs fine. When I rev up the engine and let off the gas the RPM's drop quickly, but once the engine warms up to operating temperature when I rev the engine it is slow to return to idle. It does return though.

Any ideas?

I want to get everything in order before I have to take it to the referree station to get my new VIN sticker.
