97 Taurus 3.0 L Vulcan, 103000 miles.
Hot day today in Denver - temp in high 90s, A/C running on high. All gauges
Engine started to run rough about 4 miles before I shut it off, but became
smooth again. I started it an hour later, and everything seems normal.
Shut off engine, it continued to run for about 30 seconds, stumbling. It
felt like 1-2 cylinders were firing.
No codes appeared as a result.
Does this sound like bad fuel? I use mid-grade gas, but the last fillup was
premium on 1/2 tank.
My 76 F250 V8 started surging for about 2 minutes on the freeway yesterday,
but then became smooth. Different gas station, regular lead-free. Gas
At $2.00+ for gas, are we also getting diesel fuel?
