Bird of Prey Posted October 7, 2005 Report Share Posted October 7, 2005 Have had this for awhile. I've logged with HPTuners last night. My MAP reading is 93 kPa all the time from idle to WOT. I've lost 5-7 mph and .5 et. Is this a vacuum leak? Quote Link to comment Share on other sites More sharing options...
Nate1647545505 Posted October 8, 2005 Report Share Posted October 8, 2005 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! Quote Link to comment Share on other sites More sharing options...
Bird of Prey Posted October 8, 2005 Author Report Share Posted October 8, 2005 Thanks for your reply. I'm taking the intake off again and will be checking the wiring in the back and checking the vac lines as well. Hard to believe I've lost this much power.

Bird of Prey Posted October 11, 2005 Author Report Share Posted October 11, 2005 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. Quote Link to comment Share on other sites More sharing options...
Bird of Prey Posted October 12, 2005 Author Report Share Posted October 12, 2005 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! Quote Link to comment Share on other sites More sharing options...
