Getting Fed up!
Ok...Still getting the rough riding when I get to Overdrive. Pretty sure its the injectors. Got a stupid question for you all. Places like Jiffy Lube (or any other quick oil change establishment) offer a service that cleans out your injectors right? My question is this....can anyone tell me where the port is on the intake/engine that these people would hook their machine to to clean the injectors? I figure I could do the job myself with a can of carb cleaner and save 50-60 bucks.
Call me stupid if its a stupid idea and laugh all you want...I am frustrated and running out of ideas on what may be wrong here. I dont have the(my) tools here with me and dont have the funds for a cat converter(dont think that is the major prob here)right now. I am even considering getting a can of ether and sprayin for vac leaks!
Hopefully someone out there can help me out here.
Thanks in advance and dont hurt yourself laughin! LOL!

The only way I could see them cleaning the injectors with them still installed is to use the fuel supply and return lines. I don't think you can use the fuel pressure test connection to do much of anything. I wouldn't trust places like Jiffy Lube anyhow. Way too much bad press, and have known way too many people who have had bad luck with them. Is your problem only when it shifts into overdrive? Wondering if there is a separate gearset/clutchpack in the A4LD for OD, or is yours a 5-speed? I believe there is an electrical solenoid that manages your OD in the A4LD as well, and if it has a separate gearset/clutchpack in the tranny, it may be failing. If you have exhausted all of the usual tune-up items and cleaned everything out, including the injectors and fuel system, and it's still giving you grief in OD only, then there's issues elsewhere. If it's during low-speed/low-rpm's, you may want to go ahead and check your IAC, vacuum leaks, throttle body & intake, etc. -- may be a dirty IAC/intake/TB or vacuum leak. Could also be a wearing or worn timing set (chain/gears). Could also be a stopped-up catalytic converter.
OH, and you may want to check for a banana in your tailpipe....

Its when I go into OD. So I guess I will check vac lines and elec connectionsaround the trans and case and get TB/ carb cleaner and see what I can do for now. May even go buy a timin light and try that route to. The only prob I got is findin time. BTW...Can you tell me where the Spout connection is and some info about it? Thanks for the info Kernel

The SPOUT connector is on the passenger's side of the engine, it's part of the wiring harness that comes/goes to the distributor, and it's fairly obvious, should be marked "SPOUT" in white lettering on a black connector. Sounds weird, if this is only happening when you go into OD (and I am assuming it's an Automatic tranny again here), then I'm thinkin' it may be the transmission, or at least partly the transmission. What you may be experiencing is the tranny shifting into OD, then back to 3rd(D), then back to OD, back to D, etc etc etc. Had this happen before, and it was mostly due to some out-of-adjustment linkages, but also in the process, the transmission went out. Could be just a matter of whatever RPMs your engine is running at when you get into OD as well. Have you pulled any codes at all?

The pressure relief valve.
imo, The chemical flushing is just about useless on older vehicles, especially over 100K because the injectors are worn and may be so clogged the flushing can do little to unclogged them.
You can have your old injectors rebuilt and cleaned for $25 a piece, a person has already posted about how well they work in the forum. A place in NJ does it.
> I figure I could do the job myself with a can of carb cleaner
I believe they use a stronger solvent then carb cleaner and it is feed under pressure in a small constant amount if they use the type machine that does it while the vehicle is running.
> Still getting the rough riding when I get to Overdrive.
imo (since engine feedback with a scanner is limited on ECC-IV) You need to get a tach and vacuum gauge on the engine while it is doing the stumbling while driving.

ok...gonna try to answer everyones questions...and as always have more for you all....
Thanks for the location of the SPOUT connector. Does or could it affect the entire system if its defective? No I havent pulled codes cause I havent went and got a reader from the auto store cause 1) I am cheap and 2) I was hoping to figure the problem out with all your help b4 going that route.
It is an auto trans. If the problem is there then why just the crappy running in OD? (I know I kinda asked that b4) I have never heard of this happening b4 but then again you learn somethin new everyday.
Got some TB Cleaner and some Slick 50 treatment for the trans. Kinda hesitant about the trans treatment cause it would suck if I put it in and it didnt change asnything but at this point I am trying to eliminate the obvious fixes (if that made sense)I did replace the fuel pressure regulator this weekend cause it was leaking and obviously it didnt change anything but I was hoping it would've.
Will check out all I can and follow your advice as much as I can with the limited tools and places to work. Will follow up with you all soon as I can.
Thanks again

What happens when you think it goes into OD?
There is a second operation that takes place.
Converter lockup. Are you sure it's not the lockup function that is acting up?
The Brake pedal switch will unlock the converter when touched as a normal action.
May be one of these that is causing the problem.
OD is a forth gear and can have a problem unto it'self.
What happen if you lock it out? If it clears, you have a trans problem.

I have done everything I can think of and have tried the stuff you all have told me and I think it may well be the trans OD itself. I put the slick 50 stuff in there and made sure the fluid was right level. Cleaned the TB too. I got better throttle response now but still got the OD prob but not as bad as b4 the treatment. I prob messed somethin up bein stupid and stubborn.
I appreciate all of the help you all gave me and did fix some things that needed fixed. My truck will get me to DE in 10 days when I grad from school here in VA then I will be towing her to Colorado 2 weeks after that.
Thanks again .
Hey Bluegrass...how do I check that switch you are talking about to see if it is the Problem?

It could be a bad torque converter. Which is why you need the tach and vacuum gauge. It will help eliminate or confirm the problems.
Many times the lousy running is an engine about to stall out, but, it won't because of the road speed.
Search the tranny forum using "+torque +converter +A4LD"
