Hi I recently have been having issues with my throttle almost anytime I throw it in park i have this bouncing idle even in drive and it pushes me forward at a stop i remember years back when I was cleaning the throttle out I ended up forcing the valve open not realizing that could mess with the calibration anyways I'd like to buy a new throttle and was wandering if anyone has had any luck with the ebay throttle body's here's what I'm referring to

If you forced it open years back and it didn't immedaietely cause a problem then I wouldn't necessarily think it's problematic now.
The problem with forcing the throttle is that the actuator gears are plastic and can break.
If you break them the problem is noticable immediately not years down the line.
When did you last clean your idle control valve?
I would give that and your TB a good clean first.
Don't force the TB just a goodly spray of TB cleaner will do the trick.
As for used TBs I'm not aware of a reliable testing procedure off the car but I'm sure it's possible.
Just have to figure out what pins to attach a voltage across and what voltage.
Of course you would have to get teh vendor to do that before you risk your money.
Could do with reading codes too. Might be a dodgy camshaft sensor. That can cause bucking.

Sure. I have installed aftermarket parts. Some are good, some are bad right out of the box, but I generally have good experiences with them
But they do normally throw a code. BMW 41 signal inlet camshaft sensor

i believe the credo don't buy aftermarket for the e46 if it has a plug. And I would recommend not buying new e46 parts on Amazon or eBay. If the part is any good it will be priced better elsewhere, if it is priced really well it isn't any good.

The only exception I have found is Bosch precat o2 sensors on Amazon and some body parts from Eastern Europe (genuine) on eBay.

I disagree. It's 2023 and the internet has been around for decades.
It's a global market place and if you think reputable traders are going to ignore platforms like Amazon ($513.98 Billion annual sales)
and eBay ($9.795 Billion annual sales) and restrict their activity to personal website and with local reach you're mistaken.
So the idea that you're not going to find quality product on these platforms is unrealistic.

The truest statement on earth !!! You get what you pay for !!! Cheap equals CRAP !

I am not saying that reputable products are not available on the platforms, I said they shouldn't be purchased on those platforms because they are a bad deal.

Any quality (non-aftermarket) component on Amazon will be more expensive than a European car parts retailer! Pick any part number next time you are shopping, screws, sensors, etc - it will always be more expensive or shite aftermarket. eBay is a little better, but usually, the shipping puts it over.

By the way, I am literally the most experienced person you will ever encounter with respect to online marketing and e-commerce. No joke. I created the largest personalization platform on the planet (Adobe Target) and built with my old team many of the original e-commerce sites (Nike.com, Jcrew.com, etc.). I created the term "landing page optimization" and introduced Google to the concept of randomized testing (not a joke). Trust me you have nothing to teach me about online selling.

The issue with Amazon and quality products is that the cost of selling there is astronomical (30%+), so the margins on genuine and quality parts are not there. The same holds true with all of the programmatic ad networks (Google, Facebook/Meta, TikTok, etc.). The CPA for a new customer on those can be 40%. If a retailer wants to make Amazon a channel, they have three options:

1. Sell things with built-in huge gross margins - This means source your shitty product on Alibaba for zero dollars and sell it cheap but with a high margin. That is what your "cheap" e46 parts are, and they are garbage. And that is what all those YouTube ads are about. Some aftermarket folks do this with their own products to end-run the middleman, but the margin hit is crippling.
2. Mark your product up - If your product has a high COGS, mark it up enough to cover the selling costs on Amazon (that is why quality stuff is more expensive there). Amazon has a rule about selling at the same price there as elsewhere, so the only folks who do that are usually dealers or people with no non-Amazon presence.
3. Don't sell on Amazon - You seen FCP, ECS or anyone on Amazon (or eBay)? A few did it for a bit, but they found out that there is a fundamental problem. With normal advertising, even the a**-rape that is Google/FB, you may pay $30-$40 of the first order in ad costs to sell a product with 15% margin, which means you are taken to the cleaners. However, that customer is now "yours" and if you can get the order large enough to cover it, or you can drive LTV through follow-on sales, you can afford it. When you work with Amazon and eBay, you don't know who your customer is. You can't get permission to email them or communicate with them, and you can't upsell, so there is no LTV. You have to make your margin on every sale.

For the record, the same margin issues apply to restaurants and delivery services. Restaurants get totally f***ed by UberEats et al if they can't get at least 50% of their revenue through foot traffic.

Finally, Amazon exerts ZERO control over quality or counterfeiting, so you have very little recourse.
