VSV. Bypass

Due to running marine gas in empty tank,car ran really rough...trouble shot for awhile and found VSV clogged and removed...found out that the part was discontinued.so left lines open and capped off wires comments!

 

So far so good! Only been a few hrs. Will update tomorrow!

 

Well,the truck is running fine. May be using more gas,not sure yet

 

I can tell you what is going on if you're curious. Without the valve there to block it off you'll have occasional hard starts and extreme rich cold starts because you have created a vacuum leak.

 

That's what I thought,but where do I get the part when it's been discontinued. Or what do I do! HELP!

 

I remember this happened to someone else and we figured out there is another part number from a Lexus that crosses over, lemme try and find it.

 

Yeah, sometimes just the little bracket attached to the VSV is the only difference in part number.

 

What makes you think marine gas caused a problem? It should be high octane ethanol free . . . gasoline.

 

Rock auto has an Aisin for $38: https://www.rockauto.com/en/catalog...st+&+emission,vacuum+control+valve+(vcv),4980

I think that's the right thing.

 

Ethanol free gas won't cause a problem.
