Hi, I'm confused.
I'm replacing spark plugs. Do I get platinum or double platinum? Is one better than the other? Why?
For my 1998 [ame="http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=corolla&linkCode=ur2"]Corolla[/ame] LE (with 149,000 miles) the trouble code read P0134.
P0134 = O2Sensor Circuit No Activity Detected (Bank #1 Sensor #1)
I found there are 2 types of sensors: upstream and downstream.
Do I need ONE of these or both? How do I know?
Is there a future problem created by NOT getting a DENSO brand?
Thank you, Mrs. Marti J.
