HI friends,
My 2001 Toyota Camry LE the check engine light has come and I took it to Autozone .After checking report told me that error code is PO 402 and EGR insufficent flow.Autozone asked me to pour Seafoam auto marine fleet(which cleans carbon).Now they resetted and now no engine check light and please guide me what to do.
How serious is this error code?

P0402 (EGR insufficent low detected) this is the error I got .Now they resetted .how critical issute this ?do i need to visit the mechanic immdtly?
 
Not very. It is the system that brings the unburned fuel back into the engine to be burned. It will trigger a check engine and likely would make you fail an emmission check if your state has one. If the check engine light stayed off I'd say you're good to go. If it comes back could need a new EGR valve not that hard to replace and fairly inexpensive.
