305 tpi idling issue HELP!
I have a 1985 Iroc 305 tpi and it has an idling issue it sputters and wants to stall out unless I'm on the gas pedal.. I've checked the timing, all 8 fuel injectors are reading a even 15 ohms. I replaced the fuel pump and filter spark plugs and wires. I've inspected the distributor cap and rotor I've searched everywhere for a vacuum leak and nothing is turning up. Any thoughts?

[QUOTE=Vader;6021789]Chances are that the huge vacuum leak created by the stuck EGR was the majority of the problem.[/QUOTE
Yeah just not sure as to if I should re use this egr or scrap it.. Hmmm 🤔

[QUOTE=IROC AND ROLL;6021949]And also I checked the tps at closed throttle it's not giving a reading (should be reading around 0.45 if I'm not mistaken) when I advance it a touch it says 0.80 nothing showing after that.. However it has a steady climb to 4.45 wot with no mishaps

Vader has it about a vacuum big vacuum leak. Check the hoses at the front of the manifold to the rocker cover and to the Carbon canister. They may be rotted out.
