I'm almost ready to get rid of it at this point, I have never had so many problems with a car in my whole life.

I will start here, last week my car just died out for no apparent reason and I thought it was either the fuel pump or the fuel pump relay. Well that was not the problem, I wiggled the wire for the opti-spark around & it turned over and started up. So I then took off the top plug to the opti-spark and it was completely coroded with blue crap as well as the other end on the opti. So I cleaned off the plug with a wire brush, and I got a little bit of the top of the opti with the brush as well and blew out the junk with an air-hose and then put a little bit of diolectric grease on the plug and the car ran fine for 2 days. Now I started my car this morning for a couple of minutes and when I went back outside the car had died out. I tried starting it back up and it started but with a little hesitation, then I start driving and it sounds like it wants to keep dying out everytime I stop at a light I have to drive with 2 feet to keep the car running. When I put the gas to the floor it doesn't seem to be down on power, and it doesn't apear to be missing and it doesn't backfire. I have a fuel pressure gauge in the car and at idle it reads 38lbs, but when I give it gas it does go up to about 45lbs or so. Could this be the opti-spark just going out on me?? Since there was some corrosion inside the plug I would imagine that something got inside the opti. But why would it run good for 2 days and start acting up again?? When I scanned the car the other day I got a P1?7? from what I read it was a "low resolution something code" and I saw that was an opti code, could this mean its going out?
Thanks for all of your help...

 

That was helpful

The fuel pressure is normal... should be 41 to 47 psi at idle with the vacuum line off. Put the vacuum line back on and it will drop to 38psi. When you step on the throttle, intake manifold vacuum disappears, and the fuel pressure should rise to the "no vacuum" value, and hold there through WOT/max load/max rpm.

Sounds like the Opti connections are badly corroded. Pull all the wires off, including the plug wires, coil wire and the main harness connector and clean them all up. Make sure the pins in the harness connector are all straight. Then check the Opti "test" connection, the gray connector on the bracket in the middle of the passenger side of the intake manifold. Clean that if necessary.

The "loss of low resolution pulse signal" trouble code could be related to the wiring problems, or it could be a crudded up optical sensor in the Opti. The engine will not run when that code is "active", since it is required to fire the sequential fuel injectors. When the PCM can't find the low res pulse, it shuts down the fuel pump and the injectors.
