WOW!!! I've made it. I feel like I've been through an orientation just to get to this point. I think it's a good thing though. Hopefully weed out some of the unwanted.

My problem:

I have an 85 GSL-SE and here is what I've done:

FYI This car sat for three years.

1. Before attempting to start it I drained the tank, changed fuel filter, air filter, plugs cap, rotor, oil, battery and had to get an ECU because it was missing. Car turned over and ran on starter fluid but would not stay running.

2. Found I had a bad ignitor. Replaced it and car fired right up but idled erratically.


3. Next I pulled the tank, found sludge in tank and a hole in the pickup filter and pressure washed the tank and let dry. Put in new pickup filter (modified from O'Reiley), changed all rubber fuel lines and reinstalled tank. Ran better but no change in idle.

3. Changed all vacuum lines to silicone lines and replaced all fuel/water lines under intake while it was off. Ran better but still no idle change.

4. Changed BAC valve, adjusted idle according to FSM idles beautifully now.

Now is where driveability has some issues. Before it was all about idling.

At times it would act as though it was running on one rotor. In fact, it sounded exactly like an ATV motor. I finally wiggled the injector on the one closest to the radiator and it would clear right up. ( I must add that the injector plugs practically disintegrated when I was changing the vacuum lines so I pulled out the connectors from the plug and JB welded them into the injectors. I now know you can get these from O'Reiley...DOH!!!)

5. So I ordered new gromments, O rings and caps for the injectors and reinstalled. During this same repair I noticed lots of trash in the top of the injectors so I cleaned them out with carb cleaner. I also reexamined the fuel line, filter and found lots of trash in the filter. (keep in mind I changed this filter before realizing I had a hole in the strainer in the tank) I replaced the filter, blew out the lines. Ran better but now had a hesitation or cutout under load, especially in second. Car idles and cruises fine though. It's under initial takeoff and any load in any other gear.

6. Replaced fuel pump because of, to me, excessive noise and the possibility that this 25 year old pump may be tired. New pump makes same noise and problem continues. Noise is coming from diaphram on the "out" side of the pump(what is that?)

7. Checked timing, found it off, set correctly.

Car still has miss. I might add that the cat has a hole in it and the TPS readings are off when measured in OHMS. FSM states 1.0 fully closed and 5.0 fully open. My readings are 1.0 closed and 4.64 fully open. It does however check out ok when testing with the dual LED checker. Could this be a problem especially at top end?

I hope this is clear. Please ask if you need more info. Sorry for the length. Can anyone advise next logical step?

First of all, let me commend you on an outstanding post. It is a real pleasure to see somebody actually put some effort into it.

Unfortunately, I'm a carb guy so I can't assist you other than by giving your thread a bump. I will, however, see if I can send somebody your direction.

Best of luck...
