Cant get car to idle right after gov. mod.

[anarchyx34]

I'm sure you've seen many posts like this. Long story short, did gov. mod. I added washers to put the intermediate spring in coil bind and preload the main spring a bit. I've got everything back together and I started the car. First thing it does is idle at 1500 rpms, and the rpms would get stuck after I rev it.  I did some reading and it seems that I have to back off the residual fuel screw. That would be great but mine is siezed and I broke of the end of it trying to unscrew it. So I took a dremel and ground a little of the end off (the end that contacts the throttle lever) a bit at a time until I got the revs to drop again after revving it up. Still idles high though, so I backed off the stop-screws on the fast-idle lever to make it idle lower. I alternated back and forth, ground some more screw away, and now I have it where the car idles at 1100 rpms sometimes. Sometimes it's lower and sometimes it's higher. How do i get it to idle the same place every time.

Also one thing that concerns me is that the idle drops considerably when either the a/c or power steering is used. It didn't really drop that much before. How do I get this to stop.

One more thing, I didnt touch the max.fuel screw at all during this whole procedure. Will adjustment after the gov. mod be necessary in most cases? Because while high-rpm is better than it was, it doesnt feel as strong in the mid-range as it did before. Seems to feel a little weaker all-over actually. Should I turn the max.fuel screw in a little bit?

I feel really stupid right now. My car ran PERFECT, and I had to go and screw it up. I honestly regret doing this right now and I was considering selling the car. After some alcohol I've come to my senses a bit, but i may at the least end up having to spring for a new injection pump if I cant get this all figured out and the car working perfectly as it did before.

ah the price for knowledge and understanding.  sometimes one must break something to learn more about it

don't feel bad.  injection pumps come and injection pumps go.  did you do all your searches on this forum for the governor mod?

[anarchyx34]

Yeah I've pretty much read every post I could find on the subject. Most of them ending with "that's it you're done!".

Don't worry, you are not alone. Stuff like this happens to me quite a bit. haha

I was going to attempt this mod on mine, but figured this would happen to me. Hopefully everything works out for you. I will follow this to see what happens so I know when I do the mod to my car what I might be in for.

Good luck.

I am in the same position.  I have been too chicken to touch the pump.  Even though I am dying for the Gov. Mod.  This AWY tranny is killing me.

Good luck Anarchyx34

Well I drove the car to work, which is about 50 miles, mostly highway. First things first,  when i started it up cold, the idle was lower than it normally would be, about 900 rpms. Then as I drove it a little the idle would fall back to about 1200 rpms, sometimes higher, sometimes 1100rpms. So the idle speed is something I need to work on. I'm thinking of taking a bit more off the residual screw until the idle drops a bit, and then increasing it again with the "cold start" lever that looks like a see-saw.

 Also I'm noticing that the motor feels a bit flat. It's most noticable in first gear where you used to be able to feel the turbo kick in and it was a nice (well, nice for this type of car) swell of torque. I'm imagining the max. fuel screw has to be turned in just a little bit, which might end up affecting the idle yet again. I also have been seeing less smoke than before. I used to see a little haze at night when a car was behind me if I floored it. I dont think that's happeneing any more. So somehow this mod leaned everything out?

Not sure if I should mess with the fuel screw first, or try and correct the idle first, since they both can effect idle speed?

Well I defintely got the goveror capsule and the extra lever for the cold-start idle on correctly. The aneroid lever is a different story. So you're saying my LDA might not be functional right now? Any way to check this without opening the pump back up? I imagine if I connect a hand pump to the LDA while the car is idling, the idle should increase if I give it some pressure?

edit: I just tried this, and applying 10psi of pressure to the LDA does nothing.  has no affect. So basically I have an ECO diesel now. Great.

maybe some of the linkage is not connected properly???

[anarchyx34]

Looking at this picture I cant see how I could've gotten it on wrong. Where else would it go?

[macsdub]

this is why i dont like the governor mod
the revs wont drop from high rpms

[jtanguay]

yea.. just keep tinkering around with the pump.  do not be discouraged.  (just try to be gentle with it)

read this:

had nearly the same problem as you are having.

[anarchyx34]

Any way I can verify this before taking it all apart again?

[jtanguay]

don't you have to adjust the throttle lever back a bit to compensate for the additional fuel from the gov mod??? I've never done it before but I think that might be your problem.

[macsdub]

ive done it all on my pump,its never right with the governor mod active
i estimate that i had the top off my pump 60 or 70 times tryin things to make it work correctly+let the revs drop normally from the higher revs
its fast enough anyways+pulls strong till 4400 or so anyways
even with the ach box,4400 in top gear is haulin the mail

hi guys

you're just foolin yourselves if u think that u can repeat what i do
in the shop and on my test calibration bench just on the vehicle

seat of the pants dyno and not understanding what the "gov mod"
really does will have u pulling out your hair as prev written.

send me your pump and i will do it properly and verify the results.
