  1. If it still smells ok, put it your truck. I do it every fall with left over mix.
  2. Depends what you mean by affordable. I would get a Tech 2. They run in the $250-300 range last I looked.
  3. Yea it would but don't be under the illusion that it will magically tell you what is wrong. It takes the tool, knowledge of how to use the tool, and probably a diagnostic tree. Maybe you can handle it, I don't know.
  4. My second shot was uneventful as was the first. Wife's second shot was pretty much identical to Grump's wife's experience.
  5. Again, these codes are o2 sensor heater codes only. Nothing to do with fuel trims or convertors. Strictly an electrical issue. Edit. P0154 is not a heater issue. The other 3 are. DTC P0154 HO2S Circuit Insufficient Activity Bank 2 Sensor 1 DTC P0050 HO2S Heater Control Circuit Bank 2 Sensor 1 DTC P0059 HO2S Heater Resistance Bank 2 Sensor 1 DTC P0155 HO2S Heater Performance Bank 2 Sensor 1 Without a p0430 code I'm not buying the bad convertor
  6. As of Sept. 2020 there is an update to the software. Take it in.
  7. It is mounted above the spare tire. There may be two modules stacked on top of each other, depending on options.
  8. They may well be connected. See bulletin. Document ID_ 5075841.pdf
  9. They pretty much all have the harness from what I remember.
  10. Made one out of a 2x2 and a 6" strip of 1/4" plywood. Works fine. Have to rip the 2x2 down to fit and bevel the plywood.
  11. C0800 is a voltage/ground issue. Good chance it is a cable issue.
  12. These 3 codes can only be caused by a bad sensor, wiring or ECM. You or someone needs to do a deep dive diagnostic. Whether or not they cause a rough run condition is another question.
  13. Seems to me they charged 1.0hr diag. $139.00. Roughly $800 was spent on oil pressure sensor replacement, trans flush and wiring repair. P0050, P0059, P0155 are all bank 2, sensor 1 heater codes. Shouldn't cause a drivability problem especially on a warm engine. Cats could not cause these codes. Pull the passenger side oxygen sensor in or near the manifold. Is it soot covered? possibly a leaky injector ( internal ). Here is a schematic for oxy sensors if it helps.
