Hey guys, I'm new here but not to Toyotas. You can find me usually on Yotatech as I have a 93 4runner. The reason I'm posting here is to gain knowledge from the ever-knowing LC gods. My step-mom has a 96 LC (sorry no lockers ) with 165K miles and, being the woman that she is (sorry to any women on here but yall aren't the best at maintaining vehicles) doesn't take care of her car. But before I begin with a question, I'll post a little fix I found in case someone needs it in the future. I had these codes not too long ago after already replacing the EGR modulator and the EGR itself: 0401 EGR flow insufficient detected 0402 EGR flow excessive detected 0420 Catalyst system efficiency below threshold (bank 1) The stealership wanted to replace the cat . I replaced the upper O2 sensor and got rid of the 0401 and 0420. So now after reading here, I'm going to check the lines for blockage and if needed replace the VSV. This leads me to my first question. Where is the EGR VSV? Next quick question. If the front axle is already making noise when turning, has damage already been done? Final quick question. Is it typical for the oil cooler to leak? That's where it looks like oil is coming from but I'm not 100% sure. And yes, I did search on these items. But if I didn't do a good enough job feel free to tell me with as much flame as possible. Alright flame away (and try to answer my ?s) at my lack of knowledge in this new land.
