1992 Intermittent code 44 The fix is....
My 1992 has had an intermittent code 44 - left bank oxygen sensor lean - since I bought it recently. After talking with Tom Wong, the decision was made to pour two 20 ounce bottles of Techron into a full gas tank and drive it. The thinking was some injectors were dirty and not spraying fuel correctly. After about 10 minutes of driving I got a code 44. Normal for the car. I kept driving, the "service engine soon" light went out, and I kept driving for another 2 hours. The "service engine soon" light did not come back on. This morning I cleared the code 44 and went for a 2 hour drive. I did not get any codes and the car now idles much more smoothly than it did before adding the Techron. It appears the problem may have been a dirty fuel injector on the drivers side not spraying correctly and the Techron cleaned it. The car got rained on while I was driving it but there arre NO codes. Life is good.
