Error Code 27

GTI proclaimed:

Check em again. You have a fuel injector that isn't moving when hit with a feed pulse. Or if it is moving the feedback isn't getting back properly. Might be damaged wire in the feedback if the engine is running *smoothly*. Could be a jammed injector but would expect that to cause a bit of roughness much like an injector not opening. If jammed open, you'd know it already.

Yeah it idles rough. I was thinking it could be clogged up.

It's possible that GTI accidentally swapped injector wires. Can't remember which pair but I know two of them both come out the same location on the rail. That's why the noid lights are handy.

Some shops also have the Sun tool that can watch both spark and injectors to determine what's going on.

I'd start with a noid light first.

I'd agree for reasonably normal operation above freezing, but I may have falsely presumed that the new engine did not come with new injectors... or if it did, possibly one is no good.

Jerry Bransford proclaimed:

I checked to make sure I didn't have any of the injectors switched around. The #1 and #2 injector come out of the same hole. I thought I had them backwards but I switched them around and I still have the same error code. Tomorrow is a new day nd I will be out early to see what i can figure out.

The computer cannot detect a stuck or plugged injector. It only monitors the electrical circuit integrity. There is an open or a short in one of your injector circuits. Start by determining which cylinder is misfiring, then check wiring to that injector and resistance across the injector terminals.
