my truck just had some motor work(head gasket) about 2-3 weeks ago and ever cents is hasn't ran right.. would take 6 time to get it started and wanting to cut off just a mess.. well today i went to start it and the same. start cut off start cut off and so on. when i got it to stay running it just goes full throttle like and have no control over it.. i just dont know anymore with this truck. and btw the guy i had do the work his shop just got closed down..

 

I would check the fuel pump pressure and Idle Air Control .

 

ok i will but, i was looking and i seen this. it seems to be broke and it goes behind the intake but have no close what it dose

 

anybody know what that part is/dose?

 

does the other end of that go to the PCV valve?

 

It goes into the brake booster

 

That's how the brake booster gets it's vacuum, fix it and u will it should be able to run I better believe it does to the intake though.. I'll check.. What is the vehicles info

 

its right beside where the spider injector electrical connect to on top of the upper intake..

 

is this whats making it go full throttle?

 

Start there, and see where it takes you..
