I ordered the plugs today...hope to order the coils after my next paycheck! The powertrain complaint is interesting. when it first started happening, I considered the transmission, but after paying attention to the different situations, I'm pretty sure my situation is fuel or spark.
Let me know how it goes. I have new spark plugs and a new fuel pump but haven't inspected the rest of the fuel system. I'm not sure how, tbh, so keep us updated. Good luck!
