We drove about a thousand kms on the weekend. Check engine light came on a few times. Here are the KOEO diagnostics codes after the trip:
172 HEGO sensor indicates system lean (RH). (old) 181 Adaptive fuel rich limit is reached (RH). (old) 189 Adaptive fuel rich limit is reached (LH). (old) But this is new: 186 Injector pulse width higher than expected. (this is new) Any use?I noticed the the performance dropped considerably when engine was hot. Actually one afternoon, when the humidity was high, and weather hot, the car almost was not moving uphill (engine kept running though, knocking of course). Why when the car is cool, the uphill performance is ten times better?. Could that be related to fuel pump as well?
I bought a pair of new o2 sensors, will change them soon.
