MAP, high input


Bird of Prey

Recommended Posts

I would say so, or the MAP has become disconnected from its vacumn sorce. 93 KPA is about 13 some psi, so that is almost out of vacumn. It should change with load no matter what.

 

 

I would say that or maybe a wiring gremlin, the +5V power lead maybe is shorting to the 0-5V signal wire?

 

Really the ony two things I could think of...Good luck!

I pulled the intake again last night.

While examining the seal I noticed in the connector

end that 1 of 3 pins was bent flat.

That would explain why I've been throwing a code

all this time. I replace the plugs since all the fuel the pcm

has been dumping during this time.

Man I hope this cures the ailment.

:D Man, we are cured of our ailment.

I plugged the MAP sensor first before i stuck

it in the manifold then pushed the intake back

to bolt it up. Whew! Now I can get back to tuning.

 

If you ever need any help, or a mind to brainstorm with, I've been tuning different GM platforms for a bit :) Good luck!
