Re: shaking?
well I brought the truck to the mechanic,he put it on the snap on machine and it turns out the O2 senser is lazy so I ordered a delco.by the way today I drove about 15 to 20 miles and burned more then a quarter tank of gas so I guess thats it does everyone agree.

Re: shaking?
Injector sticking open dumping fuel. It may not be that your O2 sensor was messed up. It may be lazy because there is so much fuel, it's cooling it off. You got raw fuel splattering out of the tailpipe? Check your oil, make sure it isn't going up. Injectors dumping lots of fuel will wash the oil off the side wall and then run down into the pan. It fills the oil up with gas. It's happened to someone else on here before. Eventually it may hydrolock as it can't compress the fuel. Unless it's all just running into the pan :2cents:
I've seen several web blogs where guys have their engines built and while everything is apart and the injectors are sitting, they get varnish buildup and the pintle sticks. Just a possibility. 35 years of experience should catch something like that though. Run it by them and see if they laugh at you.
If I remember correctly all three on one side inject and then all three in the other batch inject. If one is sticking open, even partially, it'll keep on filling the cylinder with fuel as long as the rail is pressurised.
One last edit.
Quick to find. They need to pressurise the fuel rail and see if it holds pressure after everything is shut off. If not, one of them is stuck open. There is a standard in the Ty manual from Helms. If it is slow you can basically compare each injector until you find which one it is. It's called and injector pulse test or something like that. A device plugged into the injector at the harness has a button it they press and it opens it for a pre set millsecond amount. They looks at the fuel pressure gauage and see how much it drops. All the injectors are to be within so close of each other. Again, this is something they should've caught if it was this obvious.

Re: shaking?
It may be that you had some stupid ****s work on your truck.
I'm gonna help you though because i feel your pain. First thing we need to do is go over some basics.Is your chip matched to your injectors? Is your fuel pressure set right? Can you smell fuel in your oil? Do you have a FP gauge?
There are 3 things that could be wrong,if you have the right chip and injectors and the fuel pressure is correct..
1. Stuck injector (see above)
2. Busted diaphram in FPR
3. Bad check valve in FP.
If you don't have a FP gauge,go get one.Autozone sells a nice one that hooks to the schrader valve, for <$40 It is critical to have one.
Next,learn EVERYTHING you can.You are your Ty's master mechanic.You are the only one that can fix it.If you keep letting retarded monkeys work on it,you will keep being disappointed.
I'm not a dick,I just tell it like it is.We here are more than willing and able to get you through your trials and tribulations,but we need some concrete information to work with.

Re: shaking?
Remembered it. Injector balance test. You'll have pressure on the rail with the truck running. Leave the pressure gauge on the schrader valve and turn the truck off. If it immediately drops, it's either the check valve in the fuel pump or an injector. There is a whole write in the Helms on how to check this without buying any parts until you've diagnosed it. Don't let a shop just start telling you to buy parts.
If the diphragm is busted in the FPR like Jimmy said, you'll have fuel in your vac lines. That diaphragm is what separates the fuel from the vac system. I wouldn't just go buying an O2 sensor yet. Seems like every mechanic that doesn't like what they see the sensor saying, the sensor must be messed up. Have Scotts4 or one of these guys run a Datamaster and get a whole picture and see how your O2 sensor readings fit into everything.
I also thought some about what Jimmy said. If they assembled you engine somewhere else, and had other projects going on, it very possible you've got different injectors scattered through out the banks. Don't know what kind of shop it was though.
I've seen them as low as $80. You may be able to get some of the guys around you to split the cost as it will be very handy with the FP gauge that Jimmy mentioned.

Re: shaking?
Get you a gauge and see what your pressures are and then shut it down with the gauge hooked up and see if it holds pressure. Let us know what you find. Sounds like you got a lot done already.
Make sure you bleed off the pressure from the gauge using the button on the side before you unscrew it and run it into a bucket or something. Put shop rags around the shrader fitting too. When you unscrew it, all the gas in the hose running up to the gauge will come out.

No follow up. Did you get it fixed? Run out of money and park it? j/k
