Question about 1991 Oldsmobile Bravada
A new distributor was installed now my idle is way too high and on the drivers side my exhaust manifold and pipe turns red hot
Your escape is a 3.0L duratec motor. Is the motor itself overheating or just the pipes? The high idle is often related to a dirty Idle Air Control module or IAC, which is located on the top of the motor near the throttle body. If you clean this, or replace it, after a few days the high idle is often times solved.

Ok guys, let's fix these things here!
Just went through this myself, so do the following:
Go to your local parts store and buy a Haynes Repair Manual.
You need to read the book first, learn how the ECM (Electronic Control Module) works. You'll see that there are alot of sensors and components that make up the fuel emissions bologna.
The nice thing about this system is not only does the ECM control all electrical functions, it also trouble-shoots it's self. When a component or sensor goes out, the ECM stores a code for that event in it's memory. You can use the Haynes Repair Manual to put the ECM into diagnostic mode and thus read any codes present.
So, all that's left is replacing what the EMC tells you too! :) Good Luck!
