2.9 motor problems
I have an 89 bronco II with engine problems. I started with replacing the injectors, fuel pump, fuel fillter, maping sensor, and idle regulator. Checked the upper intake for leaks, no leaks, checked vacuum lines, pretty sure fixed all the leaks. The bronco is still having troubles starting on the first crack. Run's really ruff with the start up, it idle's at 1500 RPM, still has good power, doesnt matter if it is hot or cold, does not want to run ez. Any ideas would be great. Running out of parts to put on it. haha

check the power brake booster for a vac leak??. the IAC could be stuck open causing the hi idle
