Hi Rob and Co.
I hesitate to jump into this thread maybe it should be on its own but...
I've been learning a lot from reading and have several issues that I"m working though. including Missing at cruise and low mpg ( 16-18mpg). Learning how to set the TS has been fun and I thank many people here who have put out such good info.
I'm waiting for another TS unit to see if a swap out will fix the MACS issue.
In the meanwhile, I figured I'd better confirm all those other sensor are okay.
Did a vacuum check with a hand held pump gauge affair this morning and the MAP sensor failed spectacularly. I surprised the engine runs at all! When it does, it runs with a high idle. I suspect, because excess air is being drawn into the manifold via the MAP sensor.. Is that even possible?
Thanks for any thoughts. David G, Seattle
