Is there anyway I can bring the idle speed of my 95 blazer up a little, its the 4.3L Vortec

 

What is your current idle rpm in neutral?

 

I have no idea haha its an automatic and i have no rpm gauge it just seems a little slow and i wanna bring it up just a tad bit

 

Define "a little slow"...? Is it stalling out when in gear? Is it acting like it wants to stall out?

Idle speed is controlled by the PCM and is not adjustable without modifying the PCM program.

 

Ha. But for some frustration you can try manually advancing the timing and watch the computer reset it back for you.

 

Say im in reverse and i give it some power and let off the gas it slows down and almost stalls but never has, i think its more EGR related then idle

 

Could be a sluggish IAC valve as well or possibly a vacuum leak that has caused the IAC to be closed more than it should be.

 

Can i check that myself?

 

A bi-directional scan tool would need to be used to adjust the IAC position and monitor the response to idle speed. It should be quick to update.

As far as vacuum leaks, you can attempt to find them with an unlit propane torch. Trace the vacuum lines and intake gasket interfaces with the engine running. Listen for a change in engine sound.

 

Its going into the shop saturday for alignment and a fuel filter and lines ill just have they check it out
