Is there a resistance spec check for MAP sensor?

I read about the oil fouling in the hose, but didn't know what to look at in DM readouts...

DM only shows kPa for MAP vacuum. No resistance check for MAP. There is a signal voltage check that is related to several codes being set. Look at page 6E3-A-52 and you will find the parameters for the MAP signal. Also shown is a kPa vs. voltage chart. Chart C1-D on page 6E3-C1-21 is the best way to test the MAP but only if you use a scan tool. ...........((((Do not attempt to test the MAP with a hand held pump or you could damage it beyond use as the IC inside is sensitive....))) I understand you didn't show a code but if you wish to check the MAP its a good place to start voltage wise.
When my old MAP went bad I had a hard time keeping the car running until the ECM substituted a MAP value and ran off of the TPS signal. (Limp mode).

The second jar of stuff didn't come from the MAP crossover / PCV's.

No such critter as MAP crossover - I meant the crossover that HAS the 2 PCV valves. Is that all that is - is the PCV plumbing? Why 2 PCV's anyway?

Injector looms - will they come up off of the back of the IH's? How?

Or does each wire have to come out of the loom first?

Injector looms?

Just a typo there - I meant 'spark plug wire' looms...

Then the PCV orifices (???)

orifices?
Or ori-feces? (they did have a lot of s&*% in 'em)
Maybe orifeceii? (pl)
