I just put in a new 1.9l AAZ NA engine into my caddy. Came w/ 1.9l injectors and 1.9l IP. The IP was timed to .91mm. Engine idles well, and around town, is just about perfect.
However, when coming off the freeway, going from say 65 to 0 (stop), the engine will die. It starts right back up and idles fine. It seems the engine is starved of fuel in this scenario. Tried to bump my idle a bit more, but does the same thing. It's like there's a fuel cutoff from high rpm to idle, but doesn't resume fuel to keep the engine idling. But then, when restarted, acts like nothing happened. What gives?
