i have bucking intermittent hesitation at a noload highway speed.
Had the same problem on my 94 pontiac.Intermittent open circuit in O2 sensor. Found it with the scanner - when missbehaving it was stuck on
0.444 volts (the bias on GM OBD1) Replaced it, and the problem is GONE.MotorsForum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
