Ford Escort 1.9L code 172 O2 sensor fault/lean I am trying to fix this problem
When i hook up the code read i get this code
172 R, C HEGO (HO2S) sensor fault/lean
The test is done with the engine running
The problem on the road is at stop light it will stall and stop running
On the highway it will drive with no problems
