I used to work at a dealer and it seems their inability to solve a simple problem and blame it on another product that has nothing to do with the PCM other than monitoring systems has created more problems than it solved.
Good luck my friend  |
I think so too. I was reading some posts in other forums about using either starting fluid or carb cleaner to find the leak. The thing is it's a very small leak and barely affects engine idle. I wonder if I spray around if it would uptick the engine still? Probably would I bet since it would feed directly in and rev it a bit.

Man, now I'm not going to be able to sleep.... |
I hate that, like when you can't remember the name of a song or an actor but it's right on the tip of your tongue. Only when the person leaves do you actually remember it.
They are putting the new PCM in tomorrow. If that doesn't fix the CEL code (which I'm pretty sure it won't) I will go over there and try the spray trick and check those hoses on the air cleaner box. Maybe one is just even loose around there from when my oil was changed last and they looked at the filter.... wait a minute ... I bet that is it. I had my oil changed and they always check the air filter when you do that. I bet they knocked one of those hoses loose on the air box.
The plot thickens. Will post more tomorrow after I go to the dealer and check it out. Thanks for the tip... I think you might be onto something.
