ZR-1 Net Registry Forums - View Single Post - Noticed something interesting on my LT5...

I searched through the service records that I have on the car, but I didn't find anything mentioning the LT5 getting removed and sent off for repair.

I did find the temp ID tag for the car when it was first delivered from the lot. Delivery date to the original owner from the dealer was 11/22/1990. Then on 12/13/1990, it went in to a GM dealer for service. 8 issues are listed (a heck of a lot for a brand new, couple week old car). One of them states "Engine RPM's surge badly - when coming off fwy wants to stall, nec. to throttle" and just below a tech wrote "Check & set min idle to specs", which I guess is all they did to fix the problem. I don't think re-setting the min idle to specs would fix bad rpm surging.

The next service record was on 8/14/92, so who knows what happened between those dates. One clue is a receipt from the DMV stating "Acknowledgement of Nonoperational Status" valid from 11/24/91-11/24/92, with an issue date of 11/27/91. License plate number listed on this matches my ZR-1. Weird for it to be put into Non-Op with it only being 1 year old, maybe it was during that time that the swap was done (if there was one)?
