how can i find a vacumn leak on a 2000 buick lasabre?
the car is not idling right, idles very high, then returns to normal, then idles high
at different times. autozone checked it said was tps, replaced it but didnt help.
now mecahinic thinks its a vacumn bad somewhere.
Do some youtube video searches for (vacuum leaks).
A dirty or bad Mass Air Flow sensor will do this. You can clean or replace it easily. See https://www.youtube.com/watch? v=paidfR2A4t0
