When the car is driven, it surges (tach needle fluctuates and surge is felt). I read the response for the 6cylinder version of this problem (in this forum), but I am unsure as to which part to replace. The check engine light is on and I suspect that the EGR valve, the EGR modulator or EGR VSV could be the culprit. There is no EGR position sensor on the 4 cyl emissions' system (5S-FE), so the cheap easy fix is not an option ; )
I have PDF files that are the Toyota training and repair manual content, so I am lucky to be able to get some component explanation and t'shooting info.
I am going to try to get a local parts store to check out the OBD codes to help with the next step(s).
I would appreciate any advice you could provide.
