After replacing fuel injectors reman. 4 NEW O2 Sensors walkers and remain throttlebody. All from rock auto and parts seems to be working great.
I went on vacation drove truck 7 hours hwy speeds and 1 week of driving no problems. Drove to another city about 7 hours away with 1 to 2 hours driving each day thru that week. Truck did turn off on highway. Restarted drove back to hotel. Drove home the next day no problem. P069E did come up drove home. Took about 4 weeks before truck threw p069e with p0191 and replaced sensor. Fixed that issue.
Also finally got the chance to replaced the spark plugs with new ac delco plugs proper plugs for the engine. What I took out the engine was 3 different types and brands of spark plugs from iridium, Nicole, and platinum, double platinum. Truck drove perfect after replacing spark plugs and pressure sensor. Pressure sensor was also wrong after market.
I have done a cranck relearn and a fuel trim relearn after driving I am still getting codes p1174 and p1175. I can not figure out what is causing those 2 codes to keep popping up. MAF Sensor seems to be correct but it is a autozone brand MAF Sensor.
