So in my 91 tpi I got this problem. Cars been sitting for a couple of days and I go to drive it runs great fast feels responsive to the throttle runs great but after ten or so minutes it starts to bog down amd lose power. Shortly after my ses light comes on and stays on. Codes are 22&24 22: tps signal low and 24:speed sensor low voltage or no activity . some dude told me I need to Advance my timing but I dont see why because I haven't touched my timing or have any serious mods. Whats y'all opinions on the codes?

 

Not connected anywhere in wire harness, but they do pass each other. Try to get a scan tool or DSO and monitor, TPS has wear points
