EGR and other emisions garbage...

how much will a bad EGR valve effect the motor? after looking in the service manual and checking the valve how it says to, ive decided mine doesnt work. in the trouble shooting section, it says that loss of power and poor fuel economy can be caused by a bad EGR valve... i suffer from both of these...

how hard is this thing to replace (looks like its just 2 bolts on the intake manifold), how much does it cost for a new one, and is this somehting i need to get from the dealer, or just any autoparts store?

on a side note, why is it that in my Suzuki Service Manuaul for my '88 Samurai, when i look at pictures of the dashboard, it has square vents? it also has the entire brake section wrong... it shows diagrams for the brake lines with only one line going to the rear axle (just like an 88.5) and i clearly have 2 lines going to the back.... whats the deal?

Re: EGR and other emisions garbage...

Mine went bad also, they are around $170 for a new one. I opted for a Weber and plugged all that other crap up with the caps provided with the Weber. It's the best money I have ever spent. I Weber is only around $320 depending on where you buy it from and make so much difference you will wish you had done it from the beginning. I still pass emmisions with the Weber also with no trouble, but we don't have a visual inspection here in GA. You can get the adapter that let's you use your stock air cleaner assembly which would make it very easy to pass visual inspections.

Re: EGR and other emisions garbage...

i would like a weber, but cant afford one right now (need to get the engine rebuilt first i guess)... so is the EGR something that i can get from any autoparts store? also, whats the deal with the oxygen sensor on the exhaust manifold? what does it do, and what would happen if i just dissconnected it?

Re: EGR and other emisions garbage...

I have a spare that you can have -- it's a bit dirty, but the diaphram works and it does not seem to have any leaks.

Before you go too far with this, try taking it off and cleaning out the carbon deposits in it. Use a Q-tip and a solvent in the passageways. You might also discover that you have a bunch of carbon in the connecting manifold passages! A new EGR won't be much help unless you remove that buildup, too. If they are clogged, plan on removing the intake manifold (new gasket - $2.50).
