SO do you have a turbo on the car or not?

 

[Absit]

You...took the turbo off..and you wonder why your car won't run?

Maybe it's the GIANT VACUUM LEAK you just created?

I just want to rage..so hard..right now..

Sounds like a troll

If you figured out how to keep from losing oil and coolant from the feed lines going to the turbo, you surely would also realize that the MAS has to meter the air entering the TB.

Saw the comment on FB, followed it here. Doubt it's a troll, just inexperience.

i took the turbo off and put a regular exuast manifold on

to replace the turbo

put the turbo back on. well in your case get a new one. then the car will start up and run great

 

[Jon6930]

even wen the turbo was on it did the same thing

....put a regular exuast manifold on

get another turbo (classifieds, craigslist, etc.) and start from there.

Have you done any kind of testing/searching to maybe help narrow down your problem?

 

[Jon6930]

my idle problem was there with the turbo. I needed to drive the car to and from work so we replaced the turbo and all of the piping with parts from a non-turbo engine. we have no intake leakes unless they are coming from the throttle body. Not sure about the throttle position sensor or the speed adjusting screw. I am using a maf sensor from a chevy v8 with a piggy back ignition system. all of my idle problems started suddenly and havent changed with or without the turbo. Any help or ideas will be great.

 

[92nolatist]

Info is good. What kind of piggy back system we talking about here? Like a MAF Translator?

 

[Jon6930]

Yes it is MAF translater and we are using a maf from a gm LS1. Not sure if we have to remove it since we are not using the turbo right now or not. We are still using larger injectors. i am wondering if we have an intake leak at the throttle boby. when we give it throttle it runs great but it will die when we let up. we have set the timing and adjusted the idle screw with little change. Maybe just a bad TPS.Not sure kinda shooting in the dark right now.

 

[92nolatist]

Okay, do you have the knobs inside the translator adjusted properly for the bigger injectors and also for a 1g?

 

[Jon6930]

yes i do

 

[92nolatist]

alright, whats your idle knob set to? Like is it turned to the left or the right? I believe its supposed to be turned to the right because the idle is the only knob that operates backwards of the other ones.

Anyone else want to jump in here, my knowlegde is a little fuzzy.

U replaced pipings from a non turbo engine on your turbo engine?
Don't know but isn't it neccesary too mount turbo engine pipings on a turbo engine? XD
