1997 Toyota 4Runner Base 4 Cyl 2.70L
Stalling / shuddering
I bought this car new and have kept up with all regular maintenance recommendations. It has approx 200k miles. Last week on the freeway, while pressing the gas, the car shuddered and acted like it wanted to stall, but did not stall. The check engine light came on immediately. It was riding very rough and continued to shudder. I took the car straight to Toyota, but they found nothing after running diagnostics.
First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA.
