I am going to drive my father's old 99 Lightning that was daily driven from 1999 when my father got it up until March of 2017 when it sat until now. In between those times, we would maybe drive it 20 miles a year but turn it on once every 2-4 weeks, it sits at 130k miles with some mods like a tune, lower and upper pulley (unsure of what size) K&N Cold Air, headers, and a Magnaflow exhaust. We got an oil change and tranny flush done 2 weeks ago and this week I changed the air filter as it was 20 years old and supercharger oil, when I drove the truck yesterday it gave me low fuel warning and read empty until I turned it off and turned it on where it went away and read full, and continued to read full even after 12 miles I drove, it then turned on service engine soon light so I plugged in the reader and it gave me 4 codes, p0460 (reads: Fuel Level Sensor A Circuit.). p1000 (reads: OBD Systems Readiness Test not complete). p0153(reads: 02 Sensor Circuit Slow Response Bank 2 Sensor 1). p0155(reads: no description avaliable.) I plan on changing the 02 sensor and fuel filter this week, but I'm mostly looking for suggestions from somebody as to what should be my next move moving forward. Another mention is that the truck runs very rich and I barely hear any super charger whine.
