Well, yesterday I replaced the bank 1 oxygen sensor (wasn't as bad as I thought it would be), and reset the computer, I think. The "how tos" say to remove fuses 4 and 11 for at least 10 minutes, I did. Fuse number 4 is for the DRL's, why remove that one? Anyway, I decided to take the car for a decent drive of 25 miles and visit a bro of mine. The car ran like crap, idle-wise. The first 5 miles the CEL did not come on, then it was on for the next 7, then off the rest of the way. Before the O2 change it would intermittently go off and on whenever. Left my brother's and the light didn't come on for 12 miles, then stayed on the rest of the way home. Didn't use the car again until this evening. Started it up and it died, started it up and it died, started it up and put my foot on the gas to keep it idling. Went to town to get a pizza (4 miles) car ran OK. Got pizza went home, came to a stop sign and car was surging. Got home and got my code reader. Here are the results: KOEO 172-Lack of heated oxygen sensor switches (HO2S-1), indicates lean bank 1. 176 Lack of heated oxygen sensor switches (HO2S-1) indicates lean bank 2. 332 Insufficient EGR flow detected. I also got a code 335 but forgot to look at the reason for it. KOER: 172 same as KOEO. 136 Lack of heated oxygen sensor (HO2S-2)during KOER indicates lean bank 2. 332same as KOEO. 538 Invalid cylinder balance test due to throttle movement during test. 536 BOO circut failure. 653 TCS did not change states during KOER. I got the code definitions from my '95 Ford service manual CD.
I know the sensor is in tight and that the plug is in good , so I am puzzled as to the results. Especially because now bank 2 is apparently acting up also. And before the change my codes were 172 and 173, which are just for the bank 1 sensor.
Any ideas??
Later. Pepse.
