2000 Grand Cherokee W/miss That Is Driving Me Crazy

[sportsman]

4.7 Engine Is Missing Like Crazy When I Start It Up. After Driving 3 Or 4 Miles It Will Smooth Out (sometimes) .the Malfuncition Light Comes On & Stays On. The Code Is Po 204 & 305. I Changed The Tps
& It Didn't Help. I Changed The Plugs,started The Engine And It Ran Great. I Drove It About 3 Mile Than Turned It Off. When I Restarted The Engine The Miss Was Back & So Was The Malfuncition Light.I'm Going To Clean The Enjectors Next. Am I On The Right Track?
(on This 4.7 Engine ,where Is The #4 Cylinder Located)?

I'm Going To Clean The Enjectors Next. Am I On The Right Track?

I'd say so.
P0305 - Cylinder # 5 Misfire
P0204 - Injector # 4 or INJ 4 injector bank output driver stage does not respond properly to the control signal.

(on This 4.7 Engine ,where Is The #4 Cylinder Located)?

Facing the front of the engine, #4 cylinder is the second one back on the left.
Cylinder # 5 is the third one back on the right.

Firing order: 1, 8, 4, 3, 6, 5, 7, 2.

If you're going to trouble shoot you should get a service manual.

I had to change the injector on the #4 cylinder. This seems to have fixed the problem. Thanks for the help.
