Hmmm? Should be keyed. Float rod could be bent tho.
So if you put the sending unit in the tank correctly it will work.... :doh:
There are two tabs, and each one goes in a slot. I thought one was just to center it. The hoses should point toward the frame/inside of the truck.
So it’s happy now?
Yes an hopefully I'm done messing with gas tanks for a little while.
Come on it’s fun......NOT!!
Drove it for over an hour yesterday, it did great and I even got in a few WOT pulls through the gears. I did stall it out again one time but I believe that was my fault and a habit I have from when it was carbed. When your driving and on the throttle the IAC motor "parks" at 30% open. As you slow down and come to a stop the intent is for it to gradually ramp down to idle as you come off the throttle. Well with the manual trans I down shift as I come to stop and I'm off the throttle. If I let the rpms drop enough before I take it out of gear its to far down for the IAC to catch it as it has already started closing while I had the truck in gear and not under throttle. Then it cant open fast enough to save it and it stalls. So I need to change my driving style a little. It possible I can tweak some settings to make it better but honestly it isnt a big deal I just can't coast down in gear under about 11-1200 rpm is all. I probably shouldnt be doing that anyway.
Made some more tire clearance today. The shocks were holding it up at zero pressure. Without them the a-arm is about 1/4 from the ground. I am going a different direction on the shock mounting though. The top shock mount needs to be roughly even with the top of the frame. I'm going to go with a regular relocator instead of those big mounts I had. I also pulled the front lighting harness for rerouting and new wire loom to get rid of the red crap.
Well I had some fitment issues with the second set of relocators that I bought. Details are here:
After all that mess I go to mount the shocks using the brackets I modified and I would have only gotten about 1" of lift over ride height, if that. After lots of measuring and checking I got them mounted up where they worked the best an give the most travel.....
Love the details accompanied by pics!! Very good info as always
I'm confused about the stalling. If you aren't letting the RPM drop down below idle, why does the IAC need time to react?
Anytime your on the throttle over a TPS reading of 3% it "parks" itself at 30% open. Once the TPS drops below 3% and the rpms drop under the setpoint (currently 1750) it starts closing over a 4 second time frame to bring it back down to idle (currently 750). So if I'm running 60 in 5th gear by the time I gear down through 4th, 3rd and 2nd the IAC has fully closed trying to get the engine down to the idle rpm of 750 becasue I'm keeping the rpms up with drivetrain/road speed. Once I stab in the clutch and throw it in neutral there is no load and the rpms drop quickly. Since the IAC is fully closed it stumbles and stalls.
To be clear this isnt a problem with the unit. Its a problem with some of my settings that I need to work on and adjust to find what works best for it in this application. You would not see this problem at all with an automatic trans and I've actually only had it happen 3 times. There is a procedure in the tuning manual that I havent done yet that is supposed to help correct this and get you to a closer starting point for really dialing it in. It comes setup out of the box more for an automatic.
I am probably going to lower my idle rpm some to about 650, the rpm where the ramp down starts needs to be lower and as a last step I can make the ramp time longer. That should correct it.
Played with the settings some an got it much better I can still stall it if I'm not paying attention but I'm going in the right direction. I put about 80 miles on it last night an went to one of our clubs weeknight gatherings...
Found the clips I needed and got the large trim piece on the gate finally.
Looks good bud
Got the clips from where?
