One problem related to engine exhaust system has been reported for the 1999 Toyota Tacoma. The most recently reported issues are listed below.
I had a 1999 Toyota Tacoma. This truck was a 2wd with a 2. 4 litre engine extended cab. The accelerator was always high. I got a few speeding tickets because of that. Even on small roads the rpm was unusually high. The mechanics also used to comment when they would do maintenance work on that truck. I lost this truck in an accident now. But please investigate this model also. Also the egr valve on this trucks go bad frequently. Thank you for investigating Toyota. I thought I had a fluke bad Toyota truck, but it turns out that I was not alone. Thank you for your help.
