2007 v6 169k miles 4x4. Motor is all stock. I am the second owner and most of the maintenance history is documented. I took this truck on a 1300 mile road trip just 2 weeks ago.
I replaced the plugs (with OEM Denso part #s) about 3 months ago at 167k because I had no history on them. They were slightly out of gap tolerance but looked to be in mostly good shape. No evidence of bad mixture or anything. I believe the coils are factory/ have never been changed.
Today the truck started missing hard at a stop light. I pulled off and gave it some gas. CEL started flashing along with VSC OFF and another indicator that I do not recall. Thankfully I was less than a 1/2 mile from work so I limped it back. Motor load (AC on, reverse, etc) seems to make it miss more.
For fear of saving the catalytic converter I didnt want to do any more road testing.
I'm hoping my OBD reader will show it is just a coil? Guessing I should replace all of the coils if one is bad. I have had some VERY noisy injectors but I hear that is common for these motors. I thought it was an exhaust leak but this forum convinced me otherwise.
I'm very thankful that it happened so close to work and not on the 150 mile overlanding trip I have planned in a few months
