The pigtail coming out of the pre89 GTE TCCS (ECU) is for the HAC sensor (High Altitude Compensation)... it's essentially a clumsy MAP (Manifold Absolute Pressure) sensor which is used to help adjust fueling when there are significant changes in air pressure. You can run without one if you live at sealevel... if you live at a higher altitude you'll be fine too as long as your dialy driving doesn't involve a lot of changes in altitude, but you will be running richer than you need to and your gas mileage will suffer a bit.
I don't to gibberish.... ....except for when I do.

lol.. when asking for help on a forum.. be very careful how you word your responses. Accusing someone like CRE of spouting gibberish the way you did could have hit him on a bad day. YOu dont want the helpful people choosing to ignore you

Haha, I just figured this was ANOTHER deleting EGR thread and CRE thought "F@$% this, I'm tired of explaining it"
OP, do a search on the forum. In fact, just look at threads from the past week. I'm pretty sure there are about 5 threads talking about deleting the EGR system, why it's dumb to do it, and how to do it if you still insist on doing it.

BTW, anyone else thinks it's funny how we all defend and practically worship a guy we've never met? Is someone starting a new religion/cult on here.... ?

yeah, you're right though, it's very weird. the koolaid is almost ready, BTW. there are worse things than deleting the EGR, but it's not worth doing without a good reason and is too widely encouraged by the ignorant masses.on some cars it makes a much bigger difference too.

I'm not the end-all of auto knowledge either. I'm ignorant of much, just know how to find the answer s and good at knowing what questions to ask. If you want brillianttalk to jetjock, jdub, ij. and others from supramania.com.... read some stuff by corky bell.
