This one is for Josh:

Ever thought of getting rid of that Webber and putting a 350cfm Holley on your 22r? I was told that this is the setup to run and it works wonders. Anyone heard of this?

When she's done with the Sequoia its "ON" F350 axles sitting on 37's but I'd like to try a pair of 80 axles with e-lockers under it.

Gotta love letting those springs go into the neg zone.

Doesn't look like enough leafs in the pack up front but says it rides well and it seemed to flex well.

 

[raevenzero]

Mine do the same. Super soft. Mine are cheap though and easy to replace. Those...not so much.

 

[kjnarmyfj]

Pull a part

 

[raevenzero]

yep. They are just stock toy rears and stock chevies. Easy to find and replace once you build the setup

no not really is the check engine light on? if so at service plug jump Ts & E1 read flashing service light.

if no light then ya have nothing wrong that the ECM manages

my bet is you are not keeping residual fuel pressure put a gauge on it to C

the check engine light been going on and of sence i got it , but i will check the fuel pressure , i have some marine fuel in line check balls can i put one on them some place if so ?

can on supply side not return

I've got the same problem. It acts like it's going to start when I hit the button and then just cranks. I have to keep bumping the start button until it starts. If it doesn't start right away, it's not going to start at all. Might be the old gas though...

 

[kjnarmyfj]

mine too, ut put puts and coughs, a few then starts ,

also ECM temp sensor not reading correct so the cold start inj isn`t
squirting or it could b clogged or NFG

Could also be the cold start injector not doing its job. Standing next to the drivers tire looking at the engine it's on the aluminum intake pointing toward the firewall (even with the letter I on EFI) with a black 2 wire connector on it. Now you only have 99 things to look


EDIT: Paul answered it also...I type to slow

understandable its COLD out there!

 

[Doable]

YES its cold today. This is not tech but the song from Dean Martin and Doris Day "Baby it's cold outside " is very fitting for today. And a great song.

 

[raevenzero]

Leaking #4 injector probably has something to do with it. That's one more thing on the list. Not a hard job, I just hate pulling the intake off. I guess it's time to swap the throttle body back to the other style anyway. I also have a somehow stripped one of the caliper bolt holes in the driver's side knuckle. I will have to drill and tap to a 1/2' standard like I did on the other side.

Stopped to help out a car that was stuck today and after it was out, I stood around and talked to some guys for awhile. I had been running hard through some snow, but it was fine after that. While I was talking to those guys it was idling for maybe 15 min before I shut it off. I didn't have the fan running, but the temp gauge wasn't that high either. When I started the truck back up, it acted like it was running on 2 cylinders...

The weird thing is that when I hit the throttle, it struggles to hold RPMs. When I back off though, the it sounds like the other 2 cylinders kick back in. I mashed the throttle to the floor for awhile and it finally took off and started running fine again. When I got home, the neighbor had is snow blower and was clearing our drive. I parked the truck in the road and shut it off so I could talk to my neighbor for awhile. When I started it back up, I could barely get it in the driveway.

Anyone had something like this? Plugs are fairly new. It seems to run fine at full throttle but seems to struggle and run on 2 cylinders at about 0-75% throttle.
