No I had not. Will do in the morning. As of now, only code popping is the too rich code. I drove it for like 40 minutes. The hose could also be too short ill try to see if I can get one tomorrow. Since I lose about 4 inches total it needs to stretch to connect to the master cylinder side possibly not having snug fit against the wall. I called autozone before they closed and tehy told me they do not rent those gages at their particular store so tomorrow ill try to call a few other autozones in the area. I will check that port tomorrow morning! Thanks

Let the car idle and spray some carb spray around the intake ports if the idle goes up down stumbles or dies. Then you have a vacuum leak. When the intake gaskets leak you can usually see the gasket wrinkled up. If you have a oriellys in your area I think they rent the fuel pressure testers also.

If that is the case, will the whole intake gasket have to be replaced?

Ok well curiosity got the best of me, went outside and tried that. No difference in the idling when sprayed on the different ports. I started at the one closest to pthe power steering pump and worked my way back and forth a couple different times. Now if I need to check any other leaks ill get more carb spray for that. Hopefully I can find someone that will let me rent a tester tomorrow or friday. Since at this time the code for the secondary injector has not come on yet, do you think that hose I messed with migth have fixed that?

I would say no since your still getting the rich code. Did you happen to move the wires going to the air injection solenoid on top of the ac compressor before you cleared the codes?Also that code diagnostic only runs on cold starts so lets see if it comes back after a couple of cold starts. Keep me posted when you get the fuel pressure.

Ok sounds good. No I did not mess with the plug on the ac compressor. Do you want me to play with it and check for broken wires?

No dont mess with it yet we will need that hand vacuum pump to help diagnose the broken wires. You really cant see the wires broken because the copper wire breaks inside the insullation from vibration over time. Lets get the rich code figured out first then we will tackle the P0420 code.

Thats fine. I figured thats what you were doing but you asked about it so I assumed it had something to do with this rich problem.

That code doesnt create a rich code we will get into the secondary air injection how it works componets etc later. Let me know what the fuel pressure is when you get it.

OK so went this morning and checked the pressure. It is bouncing between 55 and 60. Not like I believe this matters but just incase. When I relieved the pressure on the gauge it would drop to 35. Not sure if it means anything to you. But I see that is is about 10 pounds more than you said it should be. So whats the next step?

The fuel pressure is supposed to be 40-55psi so its within specs. Follow the info on what I just posted also remove the map sensor and make sure there is no carbon blocking the hole in the intake or on the map sensor. Also inspect the map sensors oring seal.

On the top of the intake by the power steering pump is the map sensor. There is a green connector going to it would be on the passenger side of the engine compartment. There is two small bolts holding it in place.

Ok this is what I have for now.

I took off the EGR Valve and cleaned it (plunger thing appears to move a little easier now)

I took off Map sensor and cleaned that.(Had a little black liquid around the seal. Assumed it was dirty carb cleaner from when checking for vaccuum leaks)

I also took off the fuel rail to see if any of my injectors were leaking. Which none were.

I went ahead and sprayed more carb cleaner and came across a spot where the engine would rev. This happened two different times in about 45 minutes. (I tried twice just incase of a fluke. Ended up being the plastic piece that goes on top of the throttle body with the two lines one that leads towards the check valve by the air pump and one behind the engine. Do you know what it is called? If not ill just search the junk yards to see if I can get another one.

This is what I have. As of cleaning, I drove around for an hour and no rich code has popped up as of now. I am not going to get too excited yet. Its late and ill go for a ride tomorrow. Obviously you said the other code is a cold start code so I will let you know what happens. ALTHOUGH I still ahve that gasping hiccup type thing when I try to speed up at times. I dont know which code would be more likely to be the culprit on that, but I was wondering as for the vacuum leak on the throttle body thing. Would that cause the secondary air injector code since it connects to that check valve? Or would it be the other code? I am starting to see a light at the end of the tunnel. Well as long as I dont get both codes lol. I will be happy with one at a time. What do you think

I dont know the proper name for the hoses that go on the side of the valve body. One hose goes to the air injection solenoid and the other hose to the canister purge solenoid.I would guess vacuum hose assembly or vacuum hose spider?That leak I would say wouldnt cause the air injection code but maybe the rich code. Also did you check the intake gasket for leaking vacuum especailly around the number 1 intake port by the power steering pump?Those engines are known for leaking there.

Yes I checked that. No leaks around there I did that the other night and last night. But the no codes were short lived. Both came back on today. I am going to see if there is a boneyard nearby with any saturns that I can try to remove that assembly from. Hopefully that changes the code. I am close to giving up cleaning it out and putting a for sale sign on it :/ I will let you know what happens with that part
