So my guess is that the Throttle Position Sensor has failed. You should get the codes read to see if there is a fault set.
Even without the CEL on there can be a problem already diagnosed.
Thanks 180.
I was just looking at buying an Autel DiagLink. Do you think an AutoZone scanner would show those codes without the CEL being on?
A quick search found new throttle bodies for $1,400 but there are plenty of used ones available.
