332, EGR fun...

[SASHO91]

Would a blocked nostril throw that code? Or would the DPFE be at fault?
The EGR valve is new, as well as vac. lines. Another thing that crossed my mind was the vac. pump (i think thats what it is), were the two lines for the EGR system plug into. Could that be a factor in this as well? If its not working, then the EGR valve wont open correctly, or vise-versa....

TIA.

Yes, my 93 would throw codes because of clogged nostrils.

It is very trivial to check the EGR ports (nostrils) in the intake manifold that when blocked, can generate a 332 code. Loosen the 8mm bolt on the hose clamp at the throttle body (TB), unclip the two fasteners at the front of the (stock) airbox and remove the upper airbox and intake hose from the engine. Prepare a metal coat hanger as a probe by cutting it and bending a 2" long tip at a 90 degree angle from the long length. Rotate the throttle plate fully open with the cam at the firewall side of the TB and while viewing with a flashlight, attempt to insert the 2" end of the coat hanger through the two nostrils, from one side to the other. The hanger should pass easily and cleanly through the holes. If no go then it is time to blow your nose.

does this fix the code for egr flow? have this code and can't get rid of it.tried cleaning egr tube and all the passages and new egr valve need more help?

Guys, Quit replacing your EGR valves because of these codes. They fail so rarely that it is almost always a waste of money to buy a new one.

Most EGR faults are either clogged ports (nostrils) or faulty DPFE sensors. Ocassionally, a faulty EVR solenoid will cause these faults.

word.. 95% of the time its clogged ports. i've had to clean the ones on the 93 twice..
