I just looked up my IROC RPO codes on the http://www.chevy-camaro.com/chevy-ca....asp?year=1987 site... There are alot of codes I have that are not even listed. Why is that?

Here are my RPO codes...

AC3 AG9 AR9 AU3 A01 A31 A90 B2L B34 B35 B4Z B84 B94
B97 CC1 CD4 C49 C60 DD8 D67 DKG D08 D34 DGM D80 D88
E5Z E7Z E9Z FE2 GW6 G80 J65 KC4 K34 K68 L98 MD8 MXD
NA5 N0D NP5 N33 N64 N96 P84 P20 QDZ TR9 TT4 T93 T96
UQ1 UX1 U21 U25 U26 U29 U79 VK3 V73 YT9 Z28 1AY 1HV
1SC 1SP 6ZX 7ZX 72B 72I 729 8NL 81Q 81U 8GA 9NL

 

Some will be for special group option packages.

 

Can someone interpret what some of the codes are that are not included on the site? OR where can I find this info?

 

You can use the RPO Decoder on here to get some help. Click on home then on the left side scroll down to the button that says RPO Decoder then follow the directions on the page. I still had to find some by looking at others copies of windows stickers. But you will find they will just say preferred option group with a number 1-3 most of the time.

 

Thanks. Going to check now.

 

Suggestion... Post the codes that do not come back. Someone here will probably know.

Of course if you do a search on Yahoo or Google, you can get most of the codes and figure them out.

Do a search like this "RPO G92" and it will bring up a ton of information.

Ok.. the codes that came back in error through the RPO decoder...

1HV Error
1AY ???
YT9 ???
N0D Error
E7Z Error

 

1AY is either dealer or customer ordered IIRC, not 100% sure

 

1HV 1987- Components of Iroc-Z Performance Package
1AY Order Modification Stock
YT9 Fleet Program Initiative C/F/G/H/J/K/M/N/S/U/V/W/Z-TRK CKGMPST
NOD Norwood Ohio Plant
E7Z Vehicle SPD-delete

 

Thanks. Although there are some options I'm not sure what they mean eventhough its been stated. Vehicle SPD delete? What does that mean?

 

E7Z is the Vehicle Speed Sensor-Delete I think it's an ignition kill chip that shuts your car down when you go over a certain speed?

 

Hmmm.. Thanks. I know I have more listed in my RPO. I will list the ones I'm not sure what they do eventhough theres been a description.
