Question type: Maintenance & Repair

Why does my 4Runner ,run good in the winter and bad in the summer

1 Answer

I have theories on this, as my boyfrind's '05 GMC has a similar issue. My theory: regular maintenance such as changing the trans fluid& filter as well as viscosity of trans fluid &/or gear oil. Higher mileage vehicles become senile.
