Rancho vx you said somthing about egr passeges clogged ,what is the remedy for this .
And thank you all for your assistance.
I believe your EGR singal and valve is working just fine. You turn the EGR on by grounding it, not sending 12 volts to it. I seriously think you would get a code if it wasn't. That doesn't mean that the EGR passages in the intake are not blocked, the ECU can't detect that problem. Even if they are partially blocked, you'll have problems. The entire path needs to be clean. Here's a link to cleaning them.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
