1992 Yukon/revving engine

[romeric]

Hello everyone,

I need some help with my truck. I have a 1992 Yukon whenever Iam in idle and set it to park the truck seems to rev up and down by itself and turns off. My truck engine has been converted to a TBI I bought it like that. I Checked the codes, and it has 3. (Code:24, 32, and 54.) I know code 32 is the EGR, but the egr location is covered with a plate. Thanks in advance, I recorded what it does on the link below.

The GM manual has the diagnostic procedures for each code - might as well start there and get those resolved. The TBI was stock - unless you meant that someone converted it to a carburetor?
