Trouble at Idle... Help please

So I began to have some trouble with my truck starting. Here are some of the conditions:
1. Haven’t driven it since early December 2017
2. Replaced the MAF Sensor and the connector (soldered and heat wrapped)
3. Replaced Throttle Position Sensor
4. Replaced Air Filter (cleaned whole intake tube)
5. Cleaned throttle body
6. Cleaned all sensor in that surrounding area
7. Replace my fuel filter

So, with that said, I am still having the same problems. It will start up, idle for about 2 seconds at a very rough idle, and then it dies out. Note: this is a 2004 with a 3.4 and it’s an automatic transmission.

It’s throwing the following codes:
P0101
P0121
P0122
P0222
P2103
P2111
P2119
P2135

I’m at a dead end, and I’m exhausting my resources, but anything helps. Thanks.

 

Take out the idle air controller and clean the crap out of it. When you think it's clean, clean it once more and see if that helps.

 

I couldn’t even find my IAC. I looked where everyone says and I couldn’t find it ‍♂️

That's because your 04 3.4 does not have an IAC.
Sometimes multiple codes like you are showing can be from a bad ground in a wire harness, not the battery cable. Check every ground connection you can find and look for any evidence of little beasts having chewed any wires.

 

Interesting, I was not aware of that. My '02 3.4 had it. It would have poor idle and die at stop lights and I would have to clean it up every couple of years once it creep over 160-170k miles.

 

Thanks for the heads up, I knew something was up when I couldn’t find it anywhere. But I will try to look around, it’s very possible something could have chewed up some wires. It’s been in my driveway next to some bushes for a few months. I’ll give that a shot. Any more help?

 

Nope, can’t find any faulty wires. Any other recommendations while I make a forsale thread?

 

from the codes that I looked up they all seem to have a common cause of the ecu not getting the signal it is expecting... I suspect rats/mice. Have you tried the "wiggle test". It is what it sounds like... wiggle the harness(s) and see if it goes away.

bump. still having this issue.

 

I know this may be a shot in the dark but how is your fuel delivery? If you rev it up and let it sit at a higher RPM will it continue to idle?

 

Surging at idle & on throttle 04

probably did this already, but it was worth a shot

 

Harness is what I would assume but if your intake is fine, which it really sounds like it is, and your harness is seemingly okay, perhaps the injectors could be causing a hang up

 

Vacuum leaks^^^^

 

All those codes seem electrical.. this seems like an electrical issue. Best to get a multimeter or someone who's handy with one to help you with this.

Dead alternator perhaps? Trying to think of easy solutions here.

 

Electrical gremlins are a pain to find. I wonder if your ECM is bad? Can you source a used one to just do the swap test? That might be easier said than done as well but with that many codes it points to that or like others said - bad wires ... somewhere! You can trace all of them and sometimes it's easiest to find them while it's running and start grabbing wires and wiggling them like glamisman stated.

 

Thanks for the help guys. Still looking into it.

 

Update:
Truck is running but will not Rev past 3k rpms. I got a new Throttle body, and all of the parts I had replaced before. My mechanic told me I needed to replace my ECU because he thought there was a short, $270 later, still isn’t revving passed 3k. I have gotten like 4 different MAF sensors, none of which were fixing the problem. I think there is a possibility that there is a mixup on the wiring on my MAF sensor connector. If anyone hasn’t replaced this on a 1st gen, 3.4l v6, please post a picture of the wiring shown from the clip side!

 

Christ bro you’ve been without a truck all this time?

 

Actually let me go snap a pic of mine I have the 5VZ
