85-Canister Purge Solenoid circuit failure. Dawson beat me to it.

RNH524

Is that anything I should be concerned about ? If so how do I go about fixing that problem or checking for it ?>

So I replace the TPS and cant adjust it to go under 1.30 ?? Also I think I found out and hopefully the reason to this and my regulator is leaking so going to eliminate that tomorrow.

If you cant get your tps to go below 1.3v I suggest you check your throttle stop screw , someone may have turned the idle way up at one point to keep it running.
If you have to turn the throttle stop srew more than 1 1/2 turns before it looses contact with the throttle its turned up to much.
You can back it off till it is not making contact then insert a .010 feeler gauge between the stop screw and throttle plate. Turn the screw until it just makes contact with the feeler , remove the feeler and turn the screw an additional 1 1/2 turn.
Now check your tps voltage.

So I just adjusted my TPS and changed the fuel filter, responding a lot better now. Still doesnt stay running, it seems like it wants to but still stalling out. Another thing is when I give it gas to keep it running my check engine light will come on than it will go off then keeps coming back on (Never did that before). Also when I try to hold it at a steady RMP it will drop RPMS and sometimes jump around but mainly just drops. I didnt get a chance to get to my regulator so its still leaking a little bit. Would that cause this to do it? If there a way to check to see if a regulator is bad or not ? I checked my vacuum to it and that was clear of gas and the smell of gas.

Does the cel flash constantly, or just turn on and then go back off

RNH524

It will come on stay on for a bit than turn off than come back on. No constant blinking, no pattern or anything like that to it.

Solving the problem! Converting to carb!

egr i would think. also check ur brake booster and any other vacuum lines u got. i like the carb joke though. haha... please tell me its a joke.

That sounds a bit extreme lol. Carb conversion is something I would only consider If I was swapping from a 4 or 6 cylinder to a v8.

When you checked your timing, did you verify top dead center on the #1 cylinder? Its possible that the harmonic balancer has spun the outer ring and you may think its in time when using a light. I would bring the #1 up to tdc using a wood dowl, then look at the harmonic balancer If its not on 0 then it spun.
