I need advice on trying to figure my 99 TJ 2.5 engine problem. I have a strong intermittent miss. The idle is some what rough. The engine cranks easily. I've replaced fuel injectors, plugs, wires, cap, rotor, exhaust manifold gasket, and inspected the exhaust manifold for cracks. The miss occurs at varying speeds usually around 1800 rpms. Under load the engine normally and will stops upon acceleration. I've spoken with several mechanics and all have a different diagnosis. Has anyone had a similar experience.
