Maybe give Rob @ Needswings. com a shout. A short call may help you solve your problem...an w/ all the $ you've invested , he probably could save you a buck or 2.. He's a Wizard....wellll @ the least a good wrench!!

 

Guys,
What is the seal called that is attached to the bottom of the engine cover that seals tight to the mas air flow sensor. I cannot find a place to buy this seal. Mine has some dry rot which may be causing a slight air leak. Anyone know where to buy this? I checked ebay but could not find a match. Thanks. Also I have the crank shaft position sensor on order. I will update after I replaced that.

 

There is a parts manual that may give it to you.

Is this what you are looking for?

 

Yes that's the seal I need to replace

 

Here are the details of the part.

Part number 112 094 01 80

 

onhundred80,
Thanks for the info on the seal, mine was dry rotted and cracked. I order and replaced it. I did help some but did not resolve the problem.
I am having a problem with the car stumbling and running rough at low idle and hitting the gas pedal at any RPM under 1500, Above 1500 the rev is strong and solid. At low idle, take off and stop signs the car almost stalls and stumbles
Parts I have changed so far
6 New coil packs
12 New spark plug wires - check and recheck all are tight
12 new iridium spark plugs
New MAF sensor (replaced 2 times)
New Cam shaft position sensor
New Crank shaft position sensor
New Relay Control Module
New Computer and programming
New seal on engine cover to MAF sensor
All new vacuum lines
New EGR valve
New fuel injectors
New TMP sensor
New Air filters
New oil change / filter
Removed entire exhaust, check for plugs and reinstalled
Checked for air leaks with WD40 and brake cleaner, no air leaks
Tested fuel rail pressure Constant 52-55 PSI even at REVs

I am not sure what else I should be looking for. Any thoughts? My next plan is to change the fuel filter and fuel pump. Maybe the pump is getting weak or the filter is plugged. Its hasn't been changed since I owned it. Does anyone have any other suggestions. This one is driving me insane. Im not sure if changing the filter or pump will help as the pressure is constant, but not sure what to do....Hair is falling out faster now

 

Did you remove the battery and tray and look under there for that vacuum line that gets eaten by overspill acid ?

 

And what is the MAP reading at idle ?

 

I'd pull the valve cover off and look for something amiss in the area of the valves, springs, etc. Just a suggestion.

 

 

Hi Guys,

I pulled the battery and tray. The only hose I saw under there was a small light grey hard plastic hose. The hose was in good shape. No rubber hoses under there.
The Live readings of the map sensor are 17.0 - 28.0 inHG
I posted a video of all the live readings on the OBDII at the rough idle, you can also hear the rough idle of the car. Video link of the data posted below. Thanks. I ordered a new fuel filter and fuel pump last night.

 

OK, great. Yes, that thin plastic hose was what I was talking about.

 

A)Have you done a throttle body reset?
1 Turn the key to the on position (just before start)
2 Press gas peddle to the floor and hold it there for five seconds, then turn the key off (do not remove key)
3 release the gas peddle
4 wait 2 minutes
5 start the car and short test drive
B) Bad throttle Body?
C) Rob suggested valve seal and you seem to be lost on that. The seal/guide (if I understand him correctly) to which he refers is circular, like a donut. Through the center the cylinders valve stems slides and it is mounted in the cylinder head. It helps seals the cylinder for compression build up and prevents oil from dripping down into the cylinder. Test by using compression gauge on cylinder #6; then compare with another cylinder. You will also be testing the valves sealing properly at the cylinder head itself. If the guide is not sealing then oil is running down the stem to the cylinder causing bad seal and the dirty spark plug you mentioned in a previous post.

 

Failure of this seal will not affect the compression as the valve will be closed and no compression pressure will be seen by this seal unless the valve has failed.
Failure of this seal will result in oil usage and I imagine poor idling due to fuel ratio issues if the seal is really bad..

 

Ok thanks guys, I will try the throttle body reset first, which I have not done yet. I just replaced the fuel filter which had a lot of sludge in it and replaced the fuel pump, what a mess. Replaced the crankshaft position sensor with a new one again. Still the same results here. Rough running at low idle. I will reset the throttle body and will then check for the valve seal. Do I need to pull off the entire head to find a bad seal or can I replace the seal just by removing the valve cover? Removing the head is a big project and have done a ton to this monster so far.

 

Completed Throttle body Rest, No luck there
Drove the car for less than a mile, and check engine light started flashing. Lost throttle power and car was surging, when i depressed gas pedal car would take a long while to get up to any speed, almost as if no gas at all.
4 codes were recorded
P0306 - Cylinder 6 Misfire
P0305 - Cylinder 5 Misfire
P0304 - Cylinder 4 Misfire
P0300 - Random / Multiple Cylinder Misfire detected

 

Was this problem ever fixed? I wonder why no one suggested testing the fuel.

 

. Sounds like the crank position sensor

 

Did you do a compression test?
