i just finished up the upper half of my 99 4.0 engine. head/valves redone, injectors cleaned, new exhaust manifold, and scrubbed the s--- out of the intake and throttle body (less sensors). re-assembled and it started right away with no problem but a rough idle as it gets warm and a check engine light! seems like its running a little rich. will auto zone it for a trouble code but any ideas?
