Need help (or ideas)
 
Alright I'm new and I need some help. I have a 94 ssei and I'm having some small but annoying issues. First off the car has sat for about a year or so.
My first question is what is the position the boost is supposed to be at when in idle and in park. Mine either sits at -10 or at 0. If I want it to sit at -10 (in which it runs smoother) I have to rev it when it starts.
Second question is that when I'm at 50 mph or higher, my tranny does a shaking type thing. It only happens occasionaly. The only problem I see with my car is that it needs a fuel filter and every now and then I got to wiggle the gas pump relay to get it to start.
II also get a weird like metally noise from the supercharger, but I know for a fact that it has been rebuilt. Oh, and I got 238 k ( I ain't complaining, the car was FREE!). Any ideas??

Congratulations! I had to pay for my 94 SSEi. :?

I'm not too sure on some of your post, but first I want to cover that the boost gauge and the surrounding gauges go all the way up, all the way down, to the center, and then they actually show a reading. Unless your car has a vacuum leak and will die at idle, you don't need to rev your engine.

Secondly, I may know exactly what that shaking is above 50mph, but first you have to tell me the RPMs at 60 and if they change when you let go of the gas and hit it again. We may have identical cars to an even greater extent.

the car is running at about 1500 rpms when in OD going bout 55 or so. maybe around 1450 or somewhere in there at 50 mph.
My boost gauge goes all the way up, all the way down and goes to +10 when it's not running. It's really weird.
I think it may be a fuel filter problem cause of the lack of fuel reaching the injectors. The fuel line is rusted all to heck where it tightens together. Also, when driving in cruise (when it works) it will accelerate and stop like a jerking motion, the only gauge giving a representation of it is the boost will go up about 5 pts and go down and go up again, like a rocking motion.

You'll probably need new fuel injectors, a new fuel filter, and new vacuum tubes. Absolutely get new vacuum tubes. Have your transmission electrical cable checked because I've noticed they start to crack from bending. Have a look at yours. It should be right under the throttle body, facing you if you're at the front of the car. You should have that at least looked at. It's a great start.

i would also suggest a FULL tune up. plugs, wires all filter, fluids, etc.

Good Morning...

Changing fuel injectors? We see an extremely low number of bad injectors. (Maybe 1 per year low). Trans cables cracking, this I've also never heard of before.. if possible please provide threads where this has been a problem.

Let's get some history on the car.
Any ideas on last tune up of plugs, wires, fuel filter.. any obvious items that you see like disconnected vacuum lines. Plugged items. Disconnected wires?

My fuel injectors were so awful at 278K miles that when I dipped them into a tub of fuel injector cleaner, the clear fluid quickly turned light gray with little, black pieces of dirt floating around everywhere. I am not one to replace fuel injectors, but when the previous owner had a shop rebuild the engine, the car came back with black fuel injectors (I'll find the post soon) that 1337ssei showed on the forum and no one recognized. I have 5 of these black ones and one OE from a junkyard. Judging from this, perhaps my fuel injector replacement suggestion is horrifically biased.

As for the transmission, here's my newly opened thread concerning that:

Unfortunately I have to second the injector issue. I also had a wrong injector in my 93 when I purchased it and had the same symptoms with the shuddering/bucking. One of my injectors was red and a totally different design. The car ran perfect after I swapped a boneyard injector in. Just wanted to put this up so it is not automatically ruled out on a possibility. ;)

Rock on! I found someone to back me up on the transmission. His post is right here, and I've opened a new post as well. Let's see how many more cars are having cable issues.

The black crud was from the OUTSIDE of the fuel injector where it protrudes into the LIM. This is normal PCV and EGR gunk. Soaking in injector cleaner will do absolutely (or nearly) nothing for the INSIDE of the injector that matters most.

We have MAYBE one bad fuel injector PER YEAR out of over 5000 members. Don't go to the bank on it.

I suggest TYPICAL troubleshooting methods first before shooting in the dark on wild chases and very infrequent failures.
