I recently replace my catalytic converter with a MagnaFlow direct fit, thinking it may have been clogged. This did not solve my problem. The car only jerks after it has been driven more than 30 minutes. It usually starts jerking once I get back into town (stop and go traffic). I have replace a handful of sensors. I plan on replacing the transmission control solenoid. How many do I need? Where is the TCS located? Thanks!
