Yes, to be honest I think the inlet manifold is going to have to come off. What a PITA.It would have been almost impossible to knock the VLOM plug loose -its your first
picture, although that WOULD cause a check engine light.
The other two are a good possibility - the one at the rear of the intake to
your brake booster is a big one- you'll have to remove the intake manifold to
"really" check it.
I'd try to actually run my hand along both of those tubes in PIC 1 & 2 while the
engine is running to see if you "feel" any air.
Long term fuel trims take some time once they are reset to get to their actual values.
Short terms bounce like a trampoline. And won't cause a CEL unless +or - 25* for
an extended amount of driving.
Make sure you didn't unplug the vacuum sensor that's along the brake booster hose ?????
Otherwise I think you might have to remove the intake to find the issue, which is what
you didn't want to do to begin with.
FWIW, whenever I do these Oil Pressure Sending Units I always do it by taking
off the intake manifold. It's a great excuse to clean all that shit out of there, get some new
gaskets in, and check the VLOM bolts as they loosen up commonly
Thanks for the pics and ideas.
Thanks. I have a flat valley.If your VLOM is flat/smooth it is the 2nd design.
The first design, built prior to April 1, 2006 contained AFM components, but were left disconnected from the ECM.
The second design eliminated the AFM components altogether.
Been out and double checked everything again. The only line I can find any 'play' in is the brake booster line, where it connects to the manifold. I can move that back and forth maybe 3/16 inch, but doing so doesnt seem to affect the running of the car.
Ive resigned to fate and booked myself a spot at my local mechanic, the intake removal and replacement is more than I have time for at the moment.
If anyone can advise on exactly which intake gaskets I will need (1st or second design) that would be awesome
Ill update of course when I can.
