[redrocket81]

ok will try that.......just about ready to donate this ol girl to the scrape pile...

NNNOOOOO!!! don't do that. where are you located, there may be a member willing to give it a good home if you decide to let her go.

[milehighbear]

redrocket, where you located? You may want to put your location in your signature in case someone is near you.

Can't believe you haven't retrieved the codes. Your computer has done half the work for you.

Half !? The computer did a lot more than that, time yourself
on one of the dinosaur fuel injection systems that have no
self diagnostics , heck you can pull codes on one of these
quicker than the Snap-on modis can turn on!

Never was good with fractions.

Ok i added my location. I will jsut take it to auto zone or adavance and let them check the codes.....ran like a champ till this.....

[FestYboy]

^ they can't pull codes on anything older than 96, so don't waste your time. besides, i've never met any of those fools who actually KNEW anything beside what the screen in ftont of them said.

Awe, give them some credit, they seem pretty good about figuring out the
closing time and break time

What did the light flash?
If you can't figure that out give us a video
of the light flashing.

sorry about the delay guys been really busy.....but i did the wire ground test thing....and i get one long blink then 7 short ones...any idea what this is

[georgeb]

Feedback System. Worst one to get because it could be any one of 13 different components that send info to the feedback system. But could be something as simple as a bad vac line. Was there another code?

[redrocket81]

No it just kept doing 7....... ill check again tomorrow...

Sheesh, code 17 would come up, george I'm the one not good with
fractions. I think Festyboy might be on this one the way it
acts, wiggling the VAF connector didn't help I assume but the VAF
door could be sticky..clean that area up good and make sure the
door is smooth to operate.

The TPS in this system is an old style and not likely to cause this
problem, however if it did turn the idle switch on it might buck
and cough a bit, you can unplug it, ignore the check engine light
and test drive to see if that symptom goes away. Additionally I
think it has its own code, not the generic "17".

Bad computer grounds on the engine can cause this.

A bad MAP sensor, goobered MAP sensor hose or carboned over MAP
sensor port can all cause this.

ANY bad ground to the o2 or anything that can effect o2 sensor voltage
can cause this. Even spark plug wires routed parallel to the o2 sensor
wire can trigger this code and cause the engine to cough.

Check all that, I have a hunch that the VAF is most likely where you
will find it like FestYboy says. report back!!

Mine threw a 17 but also the O2 sensor code. You really don't know where to start with a 17.
