If you disconnect the relays the EGR will just remain closed, or off. I still have my EGR on my car, but I just have the relays disconnected.

You would be suprised how many VAC lines and such are only there for emissions purposes. I have eliminated about 75% of my VAC lines and emissions crap.

Trust me, I know...

The only ones I'll have on my car when its all said and done are the few basic ones needed for the turbo system items.

There are only three lines you need on there.

The one from the BOV to the intake manifold, from the intake to the valve cover, and from the FPR to the intake manifold.

Also the ones for your BCS/MBC/EBC

I also spoke to my shop about them and they informed me of the same. I am assuming that there is an equivalent on the 420a as well.

and you say they are on the driveside by the firewall? i looked for them today, not really, but just glanced, and i didnt see any relays, are they lower on the firewall? perhaps under the brake booster?

I'm not sure on the 2g's. I know that they are there on the 1g's.

It's like a box and all the vac lines and crap that run behind the manifold run to it. If you trace those lines you should see it.

It should still be on the drivers side.

when your rpms drop do you hear any noises?!? especially any clunking?!?

I had that problem out of my Stealth... the crank bearings were wearing and it would drop RPMs, usually after letting off out of some high RPM driving, it would clunk (sometimes die) and when it picked up, idle really high for awhile til it regained its composure...

I also had that problem out of my Eclipse ('97 RS), but it wasn't related to bearings... it was my IAT sensor, but the CEL came on and set out that code (IAT current too high)...

And on a different perspective... I drove a Crown Vic (V8 decked out) that had the EGR code come on... I talked with some friends at Advance who said change the PCV... We changed that and cleaned the intake (http://www.partsamerica.com/ProductD...rtnumber=10003 12oz in fuel, 20 in intake[through PCV])
and the car will struggle to stay running and will smoke like a freight train, but gun it till the smoke stops... and that will clean the intake of all the crud it has... and that got rid of the CEL... you may need to clean the spark plugs or do a tuneup after doing this as it will foul them...

Those are just a few different things to think a/b, as they sound semi-sorta related...

There's no clunking coming from the car at all. I've ran that cleaner through the tank before pretty recently, like a month ago or so. Loved that stuff. I'm going to wait for and replace the PCV. Then I'll go from there. I'm really thinking that this is the problem. Logically thinking, with how the car is acting, and exactly what the PCV valve is and does, it kinda makes sense. Is it the 10th yet? lol. We'll see.

I don't think its the IAT. No CELs for that ever. However, I am going to replace that next summer just because anyways.

still might wanna pull that IAT out and check it... since it's easy to do and not really time consuming... just pull it off the back of the manifold and make sure it's still intact... mine blew completely apart before... then I replaced it... and used carb cleaner and toasted the new one...

2 days to go.... let us know how it turns out (I do believe that PCV is the problem though)

Today I got the PCV valve and installed it. These damn one don't have the Chysler logo on them, but what ya going to do, right? So anyways, while taking off the old hose going from the valve to the valve cover, it basically disintegrated. Thing cracked and was a pain to get all the pieces off. So I got some heater hose and replaced that too and with new clamps.

Car runs great as of right now. It took a couple miles to see the difference, but when I left off the clutch or pop to neutral, the rpms fall and stay there. I still haven't had the idle surge problem while driving it around also. That seems to have been the problem. I'll be going to work tonight and driving around later so we'll see if there's any problem, however, from looking at it, the PCV valve seems to have been the problem. Yeah!! FINALLY!! Thanks everyone.

+1 for me! lol

Glad to see you finally got it fixed, just hope that it doesn't come back now!

david-b · #27 01-10-2007, 04:18 PM

Looks like the idle surge is still exsistant, which now takes me to the IAC. It's all good though. Not once when driving to work did the rpms go bouncing around when I let off. They fell down to idle and sat there. Then that once I had the little surges pulling up to the light.

david-b · #28 01-10-2007, 09:53 PM

So I'm home now, damn I give too many updates. RPMs still fall perfectly, so the PCV was definitly a problem. However, the surging happens all the time. I did play with the fuel maps some today, and I have a higher % at idle then ever before. So that could contribute to it, but I'm thinking not. I'll probably pick up an IAC sometime soon, however, it's damn cold outside and it's oging to snow this weekend
