Catherine Fernia (Seattle, Washington) - 1992 Toyota Corolla
Catherine’s car tends to stutter and jerk when accelerating; it happens when she hits 20 mph in second gear and 30 mph in third. It gets worse if she hits the accelerator and stops if she puts her foot on the clutch. Her mechanic and husband have checked and changed many fuel-related parts. Also, Check Engine light comes on occasionally. Tom and Ray say it could just be clogged injectors, but she needs to get the car scanned so they can figure out what's causing the Check Engine light to come on.
