2 weeks ago I get P0141 and P0036. Oxygen sensor had a corroded wire right at the sensor. Replaced the sensor with a Bosch universal - there were no oem's available.
Last week, I got a p0128. Thermostat bad. Replaced, no more codes.
Today, I have a p2271 code. Same oxygen sensor as 2 weeks ago. Maybe the universal one isn't a good suitable replacement. I ordered an oem sensor to squash this problem.
Has anyone else run into this type of problem?
