I think my IAC may have died, does any one have one they are not using that I can borrow or buy to see if it's the IAC or some other problem. These Troopers don't have an idle adjustment screw, do they?

Any other suggestions

They do have an idle adustment screw. Disconnect your IAC and set your idle with the idle adj. screw and see how that goes. Currently I don't use my IAC. They are nice in colder weather for warmup but other then that the Troopers don't use it for much. You can do the same thing with your foot on the throttle padal.

I have one you can try, but as Lenny said it is really only useful in cold weather. Once it warms up it will run fine, I haven't had mine hooked up for two years I just reset my idle with the idle screw works fine. I will send you a PM to contact me.

Evidently, My Trooper has never used the idle adjustment and I didn't think it had one, but this is what it looks like, 2300398650104110397agalUy_th.jpg 2587027120104110397QDwHSM_th.jpg and now that I have it engaged and working, i had to make several other adjustments also. I had to shorten the cable by 1/4", I must have been idling on the IAC all along because I'm certain that the butterfly used to close completely. Anyway, I now idle again and that is GOOD.

by the way, those photos were taken using a mirror,

What is the IAC? Is it the sensor located at the bottom of the throttle body? Idle Air Control? Having surge problem and wont' start problem. Anybody have a diagram of the various sensors and what is what? Thanks. Steve

2645671480104110397FQplBB_th.jpgremember that my manifold has been flipped, the device on top & left is the IAC and the device on the side & center is the IAT/MAP sensor.

Inside the throttle body, there is an air passage around the butterfly and that passage is closed off by the IAC. If the butterfly closes fully, the IAC has to open to allow the idle air in, but if the idle air is controlled by the idle set screw, the IAC closes up and only adds to the air supply when needed.

Having surge problem and wont' start problem Suggest unplugging IAC and set idle with set screw.

Did you notice any issue with having the IAC still hooked while using the idle screw?

No, but like I said, I think my IAC is dead.

That cylinder is the reservoir for my shock.

why did you flip your manifold ? is it something that added any power ?

It was pretty easy to do andat the time, I was having a problem with oil blow by due to dusted rings and as the oil would pass from the valve cover to the intake manifold, it soaked the MAP, so flipping it let the oil get sucked in and burned. It also moved the butterfly up and forward and made it easier to access the throttle and the starter and the wiring and closer to the snorkeled air filter. I doubt there was any performance changes, just easier access to several things. I like it!!!

      Can’t figure out what part I’m missing
      By Grant
      I recently bought an axis 500 and it’s missing a box or something the plug is L shaped I’ve looked through the wiring diagrams and still can’t figure it out. The plug is located right near the battery housing

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!
