I have just completed a full 3.0 swap into my 1999 CSVT. It now has a 2001 3.0 with all the stock injectors, throttle and MAF items on it. I am working on a dummy set up for the 2.5 IMRC, it is currently not hooked up, giving me a CEL. I had some vacuum issues at start up that are now resolved. It starts and idles fine, and flat hauls when you get on it.

It has a slight hesitation from off the line, and some surging at low throttle. This causes some bucking of the car, kind of embarassing. I have only driven it 2 or 3 miles, everything seems to be good under the hood, no more leaking lines.

Any thoughts on what could be going on? I am not planning to chip the car, I have spent enough on it, I want to drive and enjoy.

Thoughts?
