Code 1130?

Thank you for responding. Great info. I replaced the idle control valve attached to base of throttle body I believe that is the same as the swirl valve. After replacing it I never thought about checking the vacuum to it. I also bought a smoke machine to try to look for a bad intake gasket that I replaced a year ago, but apparently there’s no leaks. I’ll try all the info that you sent me. It might take me throughout this week to do all that. Thank you for your time I’ll keep you posted. Mark

Okay Men. Appears I have 2 swirl valves. One valve on the driver's side of the Throttle body and the other is on the front side of the throttle body. The side valve has no vacuum at idle. At high rpm’s about 12lbs. I connected the vacuum pump to valve it won’t hold vacuum also checked voltage at plug. 13.75 volts.
Second valve no vacuum at idle or higher rpm. 14.5 volts. Using vacuum pump, the valve holds vacuum for about 30 seconds. Your thoughts? Thanks again.

Okay Men. I believe I have been miss leading. I sent a picture of what I thought was the swirl valve. Now I am a Little confused. The valve in the picture is identical to the one that’s still in the truck. This one connects to this swirl valve actuator. No vacuum from actuator. Kind of lost now on what to check. Thanks again

Hey, one more thing. When I did the leak/smoke test the eg transducer leak smoke won’t hold vacuum is this normal? Thanks

Hello. Sorry for slow response. I purchased a new swirl control valve just came in. Tried to install it having a problem, trying to get the two Phillips screws that hold it in to the intake removed Tried making a special tool to remove not going well. I think I’ll have to remove the intake manifold to complete. I’ll update you when complete. Thanks

Good morning. I found a brand-new swirl valve on eBay. After removing the old actuator, I started the truck and manually opened and closed those butterflies on the intake manifold. That the actuator would attach to. It really had no effect on which way I turned the shaft opening and closing the butterflies. To make it idle I would have to close half of the throttle body off with a piece of tape for my hand. Your thoughts. Thanks again

If if I tape off half of a throttle body opening it idles perfect. I plugged the vacuum line that runs the swirl actuator valve. Is that what you were meaning? Thanks

Yes, I replaced the solenoid that run vacuum to the actuator. I need to recheck the vacuum that’s coming out of that solenoid.

I thought maybe my intake gasket is bad. I replaced it about a year ago. My smoke test only showed the EGR transducer. Which I replaced also.

Hello Men, in the process of removing the swirl valve actuator the flange on the shaft which rotates the swirl flaps came off, might be nearly impossible to put back on because of where it’s located. Thinking I have to remove the intake manifold again to put that flange on.
I pluged the vacuum line to the actuator and opened up the flaps. Then started truck. No change with the flaps open. Next I sprayed starting fluid all over throttle, body intake, hoses etc. Nothing noted. I did a smoke leak test again. The new BPT valve produced smoke just like the old one, so I bypassed it for the test. The only leak I found was a small amount around the MAF sensor. I put a little grease around the O-ring to help seal it better. No change. With all that being said I up for another suggestion. Thank you

I was hoping with that vacuum line from the solenoid being plugged. And with the Butterfly flaps open. In the intake that would eliminate an issue with the swirl control actuator. I recheck it thanks.
