Hey guys...
I tried to post this last night but the site was down and could not get into it....:(
So...here goes. WhiteSnake is having a Check Engine on His '94 Cobra. I have got feedback from some other people. I am gonna post to ya'll what has transpired over the past 24 hours, as far as what he has done. If ya'll have ANY INPUT at all PLEASE let us know.....
Its been a real PITA and he's REALLY anxious to get it fixed...He finally got home after being on a ship for over a MONTH and the Cobra I guess was pissed cuz he was gone....:mad:
Here is his rundown from the beginning of the problem to the latest. And we realize when he did it w/ the key off, it should have been on....that was cuz someone said to do that and they meant it the other way, so just ignore that part.....
Thanks guys for your help, and if you can give any insight as to what you think...PLEASE dont hesitate!!!!
Thanks SO MUCH!!!!!!

Need a little help on this one.
I hooked up a code scanner on my 1994 Mustang 5.0 Cobra because the check engine light comes on.
The code scanner has give me a couple of numbers and I'm lost on which way to go.
First 6 times it give me a 3 digit number 332 which decoded to Insufficient EGR flow detected. And my last 4 times it only came up with 33.
My first question is what is the right code for the 1994 a 3 digit or 2 digit?
How can I check the EGR valve to see if it is working correctly?
There is a vacuum line going to it how much vacuum pressure should be there?
There is a sensor for the EGR what voltage should be read from there?
And how can I check to see if the sensor is good or bad?
Any and all help is needed.

Here is what I've come up with so far today.
I put a vacuum to the EGR Valve and it holds the vacuum good.
The hose I pulled off of the EGR does not have any vacuum. It is green in color
Where should that green hose pull its vacuum from?
Also when I pulled the electrical connector on the EGR REG there should have been voltage with the key off and there is none. When I turn the key on I get 6 volts.
Any suggestions?

111 111
1-327 AND 332
And no the engine did not stall when I applied vacuum to the EGR
there was also a question as to where the EVR Selonoid is located, but since then, I think we figured that out....

When mine was messing up I had to clean mine with carburator cleaner and put it back on and it went away. Maybe this will be of some help. Good luck
