Hi Scotty,
Thanks for your great, no BS advice. Really appreciate it!
I have a 2015 Toyota Corolla (European build). It has 115k (about 70,000 miles). My question is that after I have been on the highway, exit and then am stopped at a red light, the car has a rough idle.
I do the regular maintenance myself -- oil change, filters, plugs. Oil change every 20K km and air filter. Changed the plugs at 90k like the schedule said.
Any ideas?
thanks
Nam Singer

Check the air filter, clean the throttle body and the MAF. That's the first, cheap and easy step.
The next thing would be to look for small EVAP leaks.
If you have access to Live Data, short and long term fuel trim data would be of interest.
