When I first crank up the truck and start driving it, it seems to be flooding out bad(spitting, sputtering, bogging down). If I stomp down on the gas, it will bog for a second then clear out and tear down the road. Then it won't do it again until I cut it off and then it repeats......It's not in the tuning, and it did it with the stock fuel pump installed, as well as this walboro 255. Maybe a regulator issue? I have no idea, but its quite annoying having to romp down on it every morning just to get it to act right.

 

Slowpro....sounds to me like you got an injector leaking and puddling up on you. Especially when you say it does it after each time you turn it off and re-start it. I would normally think you have a stopped up converter but I just assumed that you either run with no cats (like myself) or run with gutted cats.

You may take each injector loose, one at a time and inspect for a broken o-ring or fuel leakage.

Give me just a bit more info on your truck and I'll try to diagnose it further for you.

 

Also, if you want....if it would be easier....call me here at work and we'll talk about it. PM me for my number...cool?

 

is it throwing any codes? Do you have a FP gauge?

 

It's not throwing any codes. I did a search and it seems that some air/fuel gauge hookups might make the pcm act crazy and dump fuel. If memory serves me correctly, it does seem that I started having the problem shorty after I hooked up the gauge. I unhooked the gauge and it cranked it a few different times. It never did try to bog down at idle, so that might have been the fix. I'm going to drive it to lunch today and see what it does.

Torque- Pm me your number and if that doesn't fix it, I'll give ya a call after lunch.

 

pull the vacum line on your regulator see if there is any fuel residue or fuel on it... you also could be pushing full pressure at idle

 

This is more than likely your problem.

 

I am quite sure that your truck is just mad at you! That is the to much Nitrous protest!

 

mine has been doing this lately too.... subscribing to find out why ...

 

I fired it up, drove it to lunch, no problems. I turned it off, went in to eat, came back out, drove it back to work....no problems. I parked the truck and drove my work truck back up here, so I'm going to pull the vacume when I get home and take a look. It stumbles right at crank, but doesn't go dead, then it falls into a perfect idle. Will update on my findings
