I get an error when driving for little while, when I turn the car off and then back on it goes away. So then I decided to hook up the FREE SCANNING SOFTWARE... I got a code 32 EGR... Also my BLMs are at 115

Should I be concerned? I mean will it screw up my car if I don't get it fixed right away?


thanks

BLM are pretty low. You must have bumped up the fuel pressure or used 350 injectors.
I don't see any ill effects from an EGR error but it's never a good idea to run around with an error code.

So was there a suggestion of what to do? Should I up the full pressure? Anything I can do to get rid of the code 32.

Read up on the DIY-PROM page. It's full of fun stuff like that.

To make a long story short, the BLM is the Block Learn Multiplier. The ECM "learns" how much fuel to add at certain RPM x Load areas. If the BLM is 115, he is running too rich and the ECM is subtracting fuel from the calculation. A BLM of 128 is right in the middle, and no adjustment is being made.

A firm on that BLM run down.
I'm at 120 BLM and I can smell the gas in open loop! Man, I can't wait to get into the swing of things with eprom burning. Finally done with finals I can focus all of tomorrow on my car!
