Help! Igniter Circuit Malfunction (Bank 2 Or #2)

[SamanthaW]

HELP.

I have a 1999 ES300 with 216,000 miles.

The problem started about a month ago. I was driving about 35 MPH and increasing speed when my car would not allow me to drive over 40MPH or 2,000RPM. I ran the code and it came back with P1305 IGNITER CIRCUIT MALFUNCTION (BANK 2 OR #2).

If I clear the code the car will usually start driving fine again. Sometimes it will not. I have found that if I clear the code, then keep the car turned off for a while (at least an hour) it will drive fine but eventually the car acts up again. I cannot afford to take my car to a mechanic but my husband is good with working on cars.

So my question is, what part needs to be replaced? Where is it located under the hood? What is the easiest way to replace it? And, what kind of cost am I looking at for the part?

I have also been randomly getting a code that is P0446 Evaporative Emission System Vent Control Circuit. Could these codes be related?

Thanks for anyone's help in advance! :)
