I would like to thank you for explaining that. I just received a 89 with that valve and was thinking it may be one issue with the truck.

Mine has almost same problem but mine revs high almost to 2800rpm and I think is the same problem also was thinking on replacing the map(maf) sensor

What's the cold start injector ? I removed my egg also and installed twisted smog from 460 efi guys to trick my eec into thinking all systems are stock
