Okay, so here's my issue. When I'm running the a/c in my truck, there is a noticeable miss or slight hesitation, especially when I'm driving to & from work on interstate. The truck accelerates perfectly and the only time I notice it is when I keep the truck at a steady rpm under 2500. I thought it might be a bad coil, so I purchased a new GM coil & swapped it with all 8 original coils - with no change. I'm going to change the fuel filter, but I don't think this is the problem either, but it's something that needs to be done.
The truck has around 161K miles and it has a Blackbear tune & 180? thermostat. (The hesitation was there before I changed thermostats) I installed a set of Denso platinum plugs and new stock wires about 9 months ago. I don't notice the miss when I'm towing our camper, only when it's not under heavy load. If anyone has any suggestions, please let me know.
Thanks in advance!
