You Are Very Welcome Sir.

 

So you are running the engine withouth a map sensor? And you are expecting it to run fine?

Not to sound harsh, but I would suggest you hook everything up like it's supposed to, then check you vacuum lines and clean iacv.
If it's still not running fine, then ask questions.

 

yea hook up the map, whether you use the one thats on the ls tb, or the factory one on the firewall, use ONE of them.

as far as idling weird. these will be your friend

but see with the map i was told the obdo didnt have one so it doesnt matter if its on or not

 

bro it does matter. thats probably why u are idleing weird. hook it up and then tell us whats going on. who ever told u that should be shot for giving false and in-correct information
