P0402 Code?
Anybody ever see this error code? I got a check engine the other day, when I started my truck it shook really badly for a few seconds, the check engine light came on, but appeared to run OK. I got out my reader, got this code, reset it and it has been fine ever since, no check engine light. The code reader said:
P0402 Exhaust Gas Recirculation Flow Excessive
Anybody ever get this or have to change out the EGR on a 5.4 liter? My truck is a 97 F150 (if you can't tell from my login id!), and I believe it is on the top and back of the intake.
Thanks!
