Default error code P0204

2002 with about 150,000 mile
Bought new and been pretty good until this year on repairs.
When pulling away from stop sign heard a crack like something actually broke
and then low rpm stumbling but seams ok once RPMs rise a bit.

Error code came up as P0204 injector #4

Which injector is number 4 (left to right so driver side ?)

Should it just be replaced due to error code ?

Looks fairly simple to remove intake plenum and access.
Any tips on replacing injectors or other thoughts ?

Left to right, 1,2,3,4 so driver side is #4. Sorry can't answer the other questions but I wouldn't think it would go "crack". They usually just get clogged.

Yea not sure why the noise but problem started right after.
First though was something broke causing a vacuum leak.

Looks like when radiator was replaced they did not seat the upper hose fully abd it rubbed off all the insulation on the wires feeding injector 4.
repaired the wires and checked continuity between the two and looked good
Unhooked battery for a while to reset.
but 4 still not firing and same error code

I checked resistance and all injectors are @ 12.4

I bought a new injector, have not installed it yet
it is also hase resistance of 12.4

A couple of questions
The injectors arn't idividually fused are they
Should I install the new injector and see what happens

Any suggestions would be great

I'm not the one to answer those questions except that it can't hurt to put the new injector in and see what happens. Hopefully if that doesn't work someone will come along with more information that can help you.

Latest on problem
Repaired wire harness, replaced injector 4, replaced plugs and wires.
checked compresson an #4 low about 70 PSI

runs the same but now also have the #4 misfire code
very ruff at idle and engine shakes a lot, seams fine as RPM's are up.
Under load once above 40 MPH you wouldn't know there was an issue.

If I pull #4 wire it idles better, doesn't shake, but it's ruff as RPM increase
The opposite of when all plug wires attached.

There is a knock when all wires connected, that goes away when I pull #4 wire. But it idles so ruff when all wires connected I can't get a feel were it's coming from
I don't think its a rod, I think it might be motor mount

would burnt valve act like this ?

Any ideas please let me know

Try spraying starting fluid along intake manifold seams at idle - if idle smoothes out, you have an intake leak.
I assume you've replaced pulgs & wires.

Was this issue every resolved? Seems to be a common issue but without an identified solution. I'm having the same issue and can't seem to solve it. I thought I had the issue resolved when I replaced the coil pack and plugs. The #4 plug was heavily fouled. I also grounded the ignition capacitor at the same time. After the replacement the car ran smooth and without hesitation. I got back into the car a week later only to have the code come back and run the same as previous. I thought it was a connector issue as the clips had broken on the #4 injector so I soldiered a new connector in but with no luck. Any help is appreciated. 04 GT w/ 90K miles

Items changed in sequence.
-Injectors replaced (Replaced prior to me)
-Turbo (Replaced prior to me)
-Verified compression
-Changed out Coilpack+Plugs+Wires
-Replaced Injector connector
-Had ECU checked out and confirmed to be functioning correctly

Next Steps
-Replace ignition capacitor (Melted)
-Verify fuel pressure

Any other thoughts to try out? The manual suggestions triggering the ECU. Can this be done using a standard OBD II reader (Torque)?

P0204 code

1. ECM is faulty
2. Open or shorted wiring harness
3. Failing cylinder 4 injector
4. Poor electrical connection

I would suggest checking the wiring going to the injector. Some members have run a jumper to see if the wiring going to the injector was bad.
