I couldnt post this into the DIY area, as it would not allow, hence posting it here.
I am fortunate enough to have a wife who owns an FTO 1995 GPX car
I am recently experiencing "Flashing N" and idle probs, and thought Id share with you what I have done so far.
1. Replace Stepper Motor
2. Replace Fuel Filter
3. Working on replacing Input Shaft Sensor
4. Use "Wyns Injector Fluid in Petrol tank to clear injectors.
5. Check all vacuum hoses for "gunk"
6. Check Alternator and wiring
7. Clean Idle Screw
Points 3-7 yet to be done (this weekend)
The following Pic shows where the Stepper Motor is, Fule filter and also the "Output" Shaft Sensor. I initiall thought this was where the Input Sensor was located, but it pays to double check and read the manual.

The following picture is the pinout for the "Output Sensor"

This pic highlights the Output Sensor - had some probs in getting it out from the top, but by going underneatht the car, I was able to gingerly leverage it out with a screwdriver.

This pic shows the location of the Input Sensor. it pays to remove the air filter and pipe so as to get to it easily. The pinouts of the sensor are also very important, given that there are two types, as the pins determine which type you require. They also idenitfy whether your car is a pre 09/95 or a post 10/95 model.

The following can help in determining this

http://www.camskill.co.uk/products.php? ... 035&i=9265 - from 10/95 onwards
Close detail show it to be a pre 09/95 model.

As to my above probs, I have spent numerous days here scouring the posts for some insigh to my prob, and believe that the above bullet points (1-6) are as far with what I know.
One of the symptoms is that when it idles when initially started in the morning, the idle is fine but as soon as the fan kicks in, the revs drop right down to almost stalling.
Also I can hear it sputter and the smell of fuel exists - have spent days tweaking the idle screw but to no avail. The issue with the Input Sensor I believe is the correct action, as I just recently also replaced the trans fluid and oil. The renown "Flashing N" is a bitch, and hope my above proposed work will resolve it.
Hope the above helps you guys anyway - once I find the prob, Ill update this post. I must also thanks dstocks for his insight and help.
Cheers
Tom
