Hello all,
My wife's 2001 lx470 sounds like it has an exhaust leak or vacuum leak. I can't find a leaky hose and it definitely has more of an exhaust smell than is typical in the engine bay. My neighbor is a retired master certified mechanic and he thinks probably exhaust but maybe intake. He couldn't look at it long, but will be able to this weekend. He feels it is fine to drive. There was no CEL for the couple of hours I and then he were checking it out.
After he left I had to move the LX forward in the driveway and then it had the CEL on. I drove it to autozone to get the codes pulled. By the time I got someone out there and turned the engine on the CEL was blinking.
It isn't stalling or revving. Just vibrating slightly more than usual along with the ch ch ch leak sound.
The codes are: P0306, P0300, P0303, P0301 with the first 3 repeated. Now to admit something stupid eventhough it was late and I was tired, I did pull a fuel line a couple of times when looking for a vacuum leak. So would that cause these codes. It was no longer blinking either after leaving autozone just solid.
Thanks for any help anyone might be able to give. This is our only vehicle right now and we need it for work and school.
