O.K, I'm having some idling problems but I noticed that my dash pot doesn't touch a damn thing...if it is supposed to prevent the throttle from slamming shut how does it do its job if all it does is take up weight and not touch anything? When I am in first gear and I let off the gas it will jerk like hell like you hit the brakes and let off really fast. Thanks

 

i got a 3VZE thats like acting the same as what alot of your previous posts have been, i have the kinks worked out but now she just idles at 1300rpm all the time and driving is wierd as soon as you hit the gas its like VROOOM she just goes.. ive gone through everything, maybe i should check this out with my truck as well

 

yeah. I would check my bro's truck since he has a 94 22re but he just left. So, is it supposed to touch or not?

 

i have no clue man, far as i know come to think of it mmine has never touched anything at all, i always pretty much just wondered what the heck it was for cuz it was just there

 

yeah. Whether it's on or off the only difference it makes is gas mileage...lol...jk. But it just sits there.

 

i know, the best way to find out is to see if theres slack in your throttle cable, if theres slack you know its good cuz its not sticking and its where it goes. i think its just another useless gadget really

 

yeah, there is definitely not slack in my throttle cable. There was before but I fixed it. I just heard that the dash-pot helps from keeping the throttle slammed shut because my throttle will stay the same if I let off (like 25mph 3rd gear) and it will just keep going then all of a sudden it will jerk hard and start slowing down. I don't think my compression has anything to do with this. I was just hoping someone could say, yes, it's supposed to touch, or, NO, it doesn't matter.

 

i think.. but im not sure.. i believe the dash pot is intended to hold the idle up between shifting gears.. JT

 

Here's a little inspection proceedure from the 93 FSM: http://personal.utulsa.edu/~nathan-b...34throttle.pdf

 

There is typically a set screw in the linkage that you can adjust in or out to contact the DP plunger. See if you have an empty screw hole nearby:

Have no clue what that is, because when I click on it and try to save it or open iit it gives me a notepad with a buch of numbers and symbols. What should I do?

Sorry, but I have no clue as to what your talking about. So, look for a screw hole? Where?

 

Sounds like you need to install Adobe reader.

 

yeah...probably...lol.

 

Are you talking about one of these holes?

 

PDF file = Adobe Acrobat reader needed, go to http://www.adobe.com/ and install it.



A screw hole in the end of the throttle linkage where it would contact the dashpot plunger when the throttle closes. I.e. look at the plunger on the DP, look at the point of the throttle linkage close to that plunger and then see if there is a threaded screw hole into which a screw could be installed to contact the DP.

I've never looked at the 3.0 dashpot setup, so can't be more specific.

 

Ah, I got it...I am downloading the Adobe as we speak. I thought I already had done that but I guess not.

Yeah, it looks threaded. So, where do I get this screw? Both the pictures above your post show where the screw is missing.

 

"its out of adjustment, stuck/broke or both the above". The dashpot doesnt do anything for driveability, its only to reduce hydrocarbons when letting off the throttle fast. Your jerking may be more to do with an out of adjusted TPS which will bounce timing around.

 

yeah, I need to adjust my tps...I think anyway. The 4crawler tps thing seems so damn complicated so I might just look at my manual and try it that way.

 

Dealer, junkyard, auto parts store, hardware store. I got a replacement for mine at the local hardware store. I used a metric allen head screw of the correct size on my 22RE.

 

Looks like you're missing the throttle stop screw, as well. You've seen the hole for the DP screw. Well, next to the DP there's another hole that will also be threaded. The stop screw is supposed to be there so you can adjust how much the throttle plate will remain open or shut when you let off the throttle or just when at idle. Quite possibly the reason for your idle problem.
