Our 1996 850 GLT is a 2.4 Naturally aspirated. We have had the codes read at the local Advanced Auto Store and there weren’t any codes that came up. The RPMs were jumping up and down so I cleaned the throttle body . It is hard to determine when this occurs but it seems that it happens when the car warms up. The car only has about 85000 miles on it and the mass air and 02 sensor were replaced around 40,000 miles.
Has anyone had similar problem? Please let me know if anyone has any ideas as to what might be wrong with it.
