Throttle Body Question

[EvilWon]

After having a few issues where my car would go into limp mode while stuck in traffic during the summer I determined that I had a throttle body issue. I order two new throttle bodies and plan to install them this weekend. After installing them do i just need to do the standard throttle relearn by turning the car to the run position, press the accelerator to the floor, then turn the car off?

I'd really really like to avoid going to the dealer since the local dealership is a pain to deal with.

I'm 99.9% sure the new throttle bodies aren't going to fix your problem. How many miles on the car?
I've got two new throttle bodies sitting here for sale if anyone needs them!

I am also suspicious about a dual TB fix....

G4 and G5 needs a tool / dealer to accurately and completely perform the relearn.

IT MIGHT DRIVE SEEMINGLY OK INITIALLY, but could have issues in certain situations.

What do miles have to do with anything?

The car has ~15k miles and is a 2013.

It's been an issue for a few years but only in certain situations where it was 90+ degrees and I sat in traffic for 30-45 minutes. From talking with Calvo he said he had seen a few cars have bad throttle bodies. I also plan to fabricate a heat shield while I have the throttle bodies off to help.

That's what I was afraid of. The car has an arrow ecu as well so I was hoping to avoid having to deal with the dealer.

I'm guessing the throttle relearn will need to be preformed with both ECU's?

If you have talked with Calvo why are you seeking advice from us mere mortals. I just love when people ask for advice and then want to discount answers they get because they already have a plan. Why don't you ask your guru Calvo how to do your relearn. Carry on.

Because he is a busy guy and I was hoping not to bother him on something he wouldn't make money on. The last time this happened I couldn't get an answer from anyone aside from him when I was stranded three hours from home.

I was optimistic that someone here would be knowledgeable and had a similar situation and I wouldn't have to bother him again.

It's times like this I really miss the LSX community. It seems like about 99% of the people on this forum a pricks.

In reality, maybe an LS7 swap is in your future?

Don't let the connotations get to you, just realize that this is a small community of folks. Most of are very helpful if you reach out to them directly with your specifics

Plastic or metal?

99% of the people on this forum are pricks? Your the prick. I asked you how many miles are on the car and your response is "what do miles have to do with anything"?
I'm trying to help you and you're a dick. Nice. You should have posted before buying the throttle bodies, trust me it's not going to be the problem. What codes is your car throwing? You wouldn't buy throttle bodies before a $20 code scanner would you?

[Arizona Vipers]

And by the way, you say you want to avoid the dealer, but if you install these, (Like JonB said above) you will need a throttle relearn, which only the dealer can do.

I believe you read my tone all wrong. My response wasn't to you about being a prick. It was the smart ass reply Special Ed that pissed me off. I guess I don't see the point of being a dick to someone for no reason. I've just been beyond frustrated with the lack of technical knowledge on this forum. It seems like the guys that are "in the know" have zero interest in sharing their knowledge. I'm not used to that mentality.

I asked a question because I didn't understand what miles had to do with the issue. It's unfortunate you can't read someones tone when making a post. I answered the question in the next line.

The error I'm getting is a service a service electrical system. The car seems to shut down one entire bank and will barely run. It is not a code I can clear with a typical scan tool. My go to has been disconnecting the throttle bodies and allowing the car to cool down for an hour or so. Before starting the car I do a throttle relearn. After starting the car everything seems to be fine.

This has only happened about 3 times over the past 2 years but the last time it did I decided to finally fix the issue.

I've got a call in to my local tech but I'm sure it will be several days before they call back (which is why I was hoping this was something I could deal with myself).

If anyone has interest in helping thanks in advance. Otherwise I guess I'll figure it out on my own.

As AZ says on a Gen 5 you will need the dealer to do a throttle relearn if you change the throttle bodies. I would agree with others though that it seems unlikely this is the problem. Not impossible I guess, just unlikely.

There are several things that might cause the problem. Check connections to the PCM and make sure they are tight. Do you have headers? If so and if your wiring harness is not properly insulated you could have melted wires internally causing an intermittent problem. The outside of the harness typically looks ok but wires on the inside could be melted. I have first hand experience with this. You can start the car and then move the harness around if you have a melted shorting wire it is possible that the movement will trigger the issue. Also check all grounds.

Good luck.

Damn, and I tried to help you with no chance of making $$..... I sometimes pride myself on being a bit PRICKLY !

Do you have a code scanner? It will find and give more details than the one on the dash.
This one is super cheap and works great- https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 and you can get it in 1 day.
give us actual codes that it shows and we can start narrowing things down. There are tons of things that can go wrong with these cars, but I've never seen anyone have any issues caused by bad throttle bodies yet.

That comment was directed to calvo not you. I have actually bought several parts from you.

I am with you, why not find out the source of the CEL/limp before performing multiple fixes hoping something works.

[EvilWon]

When I ran the code I got:

Unknown Diagnostic Trouble Code
Throttle Actuator Control System - Forced Idle
Throttle Actuator Control System - Forced Limited Power
Throttle Actuator "B" Control Motor Circuit Range/Performance

The last code is what makes me think it's an issue with the throttle body itself. As I mentioned before it sounds like it almost shuts down an entire bank. The car will idle rough and if you try to give it more then 5-10% throttle it really struggles. Anytime it's happened I've never driven the car more then a mile before turning it off.

In my 4 years of owning the car it's only done this 3 times. All of them were after driving the car fairly hard and getting stuck in traffic.
