Timing question.

Try clamping the dashpot's actuator down with a zip tie, then go for a drive. The only thing that'll happen with the dashpot's plunger rendered inactive is that the engine with spike rich when you dump the throttle... the car may jerk a little (try to slow harder than usual) at that point.

If the idle returns to normal and the TPS is properly set, and the code 51 is gone, THEN you may proceed with setting the timing.

When applying pressure to the dashpot it seems like it's going to kill the engine.

Really? Were you or were you not doing something to manually adjust the idle? If so, then I'd start with trying to undo it.

Well it never killed it but it wanted too it seemed.

I think I undid everything this last time around. Battery disconnect.
Hooked it back up. I was still throwing 51.

Went out and adjusted the dizzy, locked it in on 10. I set the idle screw back to where it was in the 1st place before doing so.

I"m still missing something and now I'm just too tired to keep thinking about it. Even though I want to. As it sits right now. It's in time and has no codes.

I'm about to have my last smoke of the day and call it quits till tomorrow.

I have just the zip tie for your project and I'll play around with it all day again, I'm sure sinse it's not done yet.

Why can't my dashpot just need to be replaced?

Alright, alright.

All fresh and revived. I have a new dashpot on order.

I'm going out to find that gargantuan zip tie. I sware it's 3 feet long.

Try this shite out and hope to tell toyo to stick that new part back up there inventory shoot.

UPDATE:

I did the zip tie trick. I drove the car through the subdivision twice. The car ran goos but idles at 2,500 rpm.

SO now I'm going to remove the zip tie and adjust the timing accordingly.
After I zip tied the plunger down. I was throwing code 51.

So I guess I should have took it off and then pulled codes before I posted.
But that's where I'm at with it.

I'll be back in a bit.

Alright, Gents.

I removed the kong zip tie from the dashpot.
I placed a thick towel around and underneath the throttle body, and pb blastered the hell out of the entire thing and worked it by hand with the car off and battery still unhooked.

I hook up the battery and yes the jumper wire. I also go ahead and try to save a few steps and hook up the timing light.

SO I turn the key and she's flashing no codes. I didn't even start the thing I cam up here to post. The plunger on the dashpot does seem more responsive than it did before the zip tie. Did it cure it?

I don't know I'm going to go and start it and check the timing and see where she's at but it seems to be flowing well.

Thanks again guys.

Just wondering if you ever checked the TPS resistances to make sure it was sending the right signals to the ecu. And if you do have to calibrate it you need to remove the throttle body to do it correctly.
