Hi guys I need some suggestions regarding a 1996 suburban 4wd.
Here is what I am having trouble with:
Driving at speed, 55 or higher, when I let off the gas, the tach shows rpm still at 1600 to 1900 rpm with foot off the gas pedal.
Obviously this makes stopping real work. So, I knock the transmission into neutral, coast to a stop, and once the speed drops to zero, the rpm drops to idle.
I have checked all vacuum lines, changed the mass airflow sensor, sprayed the whole intake with brake cleaner to check for leaks, no help.
Am I missing anything? This thing is too dangerous for my kids to drive right now and is seriously going to wear out my brakes.
Mileage on the car is 196K. It is a vortec. Runs like a top. No missing, no check engine lights, analyzer shows an occasional O2 sensor but that's it.
Suggestions?
Thanks in advance folks!
