Hey, I would appreciate any input on this. When ever I go to start my car in the morning it usually takes 2-3 revolutions before it catches, i'm not exactly sure if that's normal, but the real problem is immediately after I depress the gas pedal still in park the car suddenly idles erratically and struggles to stay running then shuts off. Then when I go to try and start it again it takes 4-5 revolutions of the engine to start as if it is being starved of either gas, spark or air. What could be the problem? Tps, iac perhaps? The only time this does not occur is whenever I leave the car idling for at least 5-10 without touching the gas pedal then it behaves and I can rev it in park without it shutting off on me. The injectors are clean, new distributor cap, fuel pump is working, I can't figure it out.

It is your EGR valve. Try cleaning it, rather than just replacing it. It is not cheap.

Could incorrect attachment of the tubes that run to the egr valve cause this problem? i recall disconnecting them all at one point in time and I'm not certain if i reattached them correctly,but wouldn't that throw a cel? my last cel thrown before clearing it threw a"target idle not reached" code. does that have anything to do with the egr? my local self serve junkyard has them for $6 dollars a pop so getting another one is no problem if mine happens to be faulty.

Incorrect attachment could have adverse effect on the EGR operation, but you said there is vacuum present on the port. So, I am assuming that they are installed correctly.

Believe it or not, EGR operations for the most part won't set the CEL specific for EGR. It will only points to either idle or emission problem.

If the junkyard has one for $6, I would just replace it. Just make sure that you get the solenoid as well.

From the picture, it looks right. That hose should go towards the vacuum collector at the firewall.
