Question about 1992 Buick LeSabre
1992 Buick LaSabre. Automatic. 136K mi. Accelerating, driving over 60, or going up a mild incline gives an intermittent hesitation. Puh, puh, puh, and loss of power. Mid grade fuel helps a little. High grade fuel offers no additional help. Driving next to a wall, I do hear pinging. Gidagidagidagida. But it seems to be able to ping without necessarily the hesitation. Driving up an incline, I get both. GidagidagidaPuh.. GidagidagidaPuh.. GidagidagidaPuh.. GidagidagidaPuh..
I thought about changing the knock sensor. But it is expensive. No check engine light. Is there a way to test the sensor? Is it possible for the sensor to be bad without a check engine light? Has anybody fixed this same problem?
Sounds like what happend to my 92 it was the crank sensor

I had this problem. We changed the sparkplugs and fuel filter, and have not had an issue since.
