I have recently become the owner of a 2000 LX470. It’s the Gold edition, (Air-ride, sunroof, leather, AWD, V8, etc) This girl has had several timing belt replacements, and has been kept up very well. It has had several because the previous owner had it replaced once, and then the tensioner broke after replacement. He then had it changed out again. Any how, I’ve began to notice a lack of power and a straight up misfire on cold start only. This only happens when it is below Normal operating temp, and it is enough of a misfire that I can feel it stuttering, and it has a very strong hesitation to accelerate. It has new plugs, new fuel filter, And new air filter. It also has no stored trouble codes, and does not trigger a check engine light, as well as any other in dash monitors, and has not since this began around 3-4 months ago. Please give me a word of advice!!
My daughter totaled her 95 so we found a 96 and put the much lower mile engine in. Engine runs fabulous just like in the other car. After a few hours of running, the engine light comes on. Nether LS had codes before the swap Checked codes and get these: "PO450 Evaporative Emission System Pressure Sensor Sensor/ Switch" and "PO430 Catalyst System Efficiency Below Threshold Bank 2". .
What I could find on out there was limited but I believe the 96 had an emission system that the 95 did not. I still have the 95 as a parts car so looking for best options to turn the engine light off for these errors. Again, engine runs fine and she is driving it every day.
Thanks in advance for any assistance.
I recently purchased a 1997 Lexus ls400 coach edition with 176k miles. As we were driving it home, the check engine light came on. We took it in to a shop that we've been going to for years and got a reading. They said it was the catylitic converters and that they needed to be replaced in order to pass inspection in Virginia. Since that shop only used brand new parts, each converter would cost around 2 grand. I started looking for cheaper alternatives and found some on rock auto and carparts.com for around $42-300 and was wondering if those would be a good idea to buy. Most of the ones I found had warranties so that would lessen the risk.
