What MPG With a 7730 Conversion? (Page 2/2) olejoedad MAR 29, 10:45 PM And check the readings from your oxygen sensor. fierofool MAR 29, 11:06 PM One of the club members ran a real-time scan for me at the last club meeting. He said something about the oxygen sensor, but I didn't catch it. The injectors were maxed but still lean. Fuel Injector Connection had spec'd them at 17 lb, but I later found they were actually 14. The oxygen sensor is less than a year old, but I'll have it checked again when I get the replacement injectors installed.
