2000 323 Throttle Body Blue/Yellow Label?

I was told by the guy I bought my car from that when selecting the throttle body I needed to get one with a blue label. The one I ended up with has a yellow label - the guy I bought it from said they were interchangeable. Does anybody know if that's the case?

My car is running good with it but gas mileage seems to be a little off and my girlfriend said she got the EML light for a while when driving it yesterday. I didn't see that but did get a service engine light but that often will clear up after I fill up the tank.

Thanks in advance for any assistance!

Blue label? Yellow label? This isn't a liquor store. Where did you buy your throttle body?

Also, why was the seller telling you about which throttle to select? Did he say it needed replacement? Next time your EML or SES light turns on, get the codes pulled. Any car parts store should do this for free.

LOL! I bought it from a guy I met via this forum - he knew my car and had worked on it for the previous owner.

The guy I bought it from did say it needed replacement and knocked off a few hundred bucks to cover it. Again he said get the one with the blue label but I don't know what the difference is if any. Car running well but definitely using more gas. Should probably have followed advice...

My GF had the car last time the EML light was on and it had cleared by the time she got home. Filling the tank cleared the SES light. Next time I get either I will get the codes read and post them here.

Thank you,

My throttle cable broke off the throttle body - the cable did not break, the part on the T Body where it attaches to did. I am searching for a replacement TB and I encounter the same thing... yellow or blue. Have no idea what the difference is.

HAL --- any updates on your repair?.. did you change to the blue?....
