She's a couple things UNSAT, ... I guess?
Got my new sticker.
Ck Eng Light: OFF
2 Codes showing:
a) Tranny Shift Delay
b) Oil Pressure Sensor's

She's lubed, running like a raped ape and clean inside!
Every EVAP component, ... inc/ Charcoal Box and that friggin' FUEL TANK PRESSURE SENSOR, ... (Where I lost a lot of time extracting the 'Probe-end' of the Sensor which remained behind from the Sensor Body), ... REPLACED !

I have a SERVICE VEHICLE SOON warning on the Scoreboard by the Tach.

Even after taking the Monte to a GMC Shop to see the guy who knows the secret prayer; or whatever !

Would the Forum Experts please chime-in with where to look and what to try?

How is that warning reset or deleted?

Best advice, take it to a shop with a GM Tech II Scan tool (dealerships have them and so do some other shops). Have them scan it to find out what the code is for.
