Well i changed the coil spring today. So i figured working on the car might aswell put the rest of the refurbished injectors in it. So long story short damn thing will not idle worth shit. Seems to be running rich. I have on o2 sensor not hooked up from previous owner. Not sure if that is causing this issue? Ran fine at idle before i put the rest of the injectors in it. Now it acts like a vacuum leak but as far as i can see all the hoses are hooked up like before. The car has no cats just headers to h-pipe to thrushers. Don't ask that is the way i got it. So what could be causing this issue? Has me stumped. Ok would the hose running to the pcv valve became unhooked from the intake when i installed that last injectors tonight be causing this issue i am having?

If the O2 sensor is one of two before the cats then that is a possibility but pcv line not connected will def cause idle issue.

Well i am taking the intake back off tonight to make sure nothing got caught under the gasket causing it leak. I know it will run very rough or die when it gets way to much air. Hoping this will fix the problem.

Well found out the egr valve was loose. I thinking that was the issue but will not know till i start the car up tomorrow after work. Also back window is leaking and is dripping inside the car. LOVE PEOPLE WHO CAN'T SEAL A FRIGGIN WINDOW. So more fun.

Ok up and running. Intake was no sealing to the motor causing major vacuum leaks. Fixed that. So it runs ok and good enough to drive now. Sometimes it bogs down but i know a couple of things still need to be fixed right but that will have to wait.

Installed new o2 sensor on drivers side helped the idling. Couple of other things and some interior modifications and she will be like new. Yeah i have to keep it now to much time invested to sell it. Running till she dies and then comes the 5.0 swap.
