High Idle Problem and PCM Relearn
#11
Thanks Captain,
I a have a replacement coming in. When we put the first spyder in
we were pretty careful placing the manifold down over the injectors.
It seemed a little tight/snug but everything bolted down nice and neat.
Tomorrow/Saturday when I put the next one on I will pay very close attention
to the fit. I will let you know how it reacts compared to the first one.
I do have a scanner that records live data but at this time the spyder is acting perfect.
If it happens again I will be sure to capture the moments.
Thanks - Mark K

As long as you didn't clear the P0302, the freeze frame data should still be there.
Before you install the plenum, oil the oval shaped O ring so it slides all the way up into the plenum.

Freeze Frame Data
Hello Captain,
I put the new spider on today
and got the freeze frame data
before I cleared the code.
Car is running nice. Quick off the line.
It seems like the Idle Air Control is
doing a better job. The car goes down
to a slow idle naturally now. My friend
had a scanner that was able to set the counts
on the Idle air control.
This was my freeze frame data
and I don't know how to interpret
any of it.
P0302
ABSLT TPS % 1.9
ENGINE SPEED 1443
CALC LOAD % 6.2
MAF FLOW GR/SE 13.08
MAP KPA 39
COOLANT 194
ST. FTRM 1% -4.6
LT FTRM 1 % 19.5
ST. FTRM 2% 19.5
LT FTRM 2 % 25.0
ST. FTRM 3% -12.1
LT FTRM 3 % -7.5
ST. FTRM 4% 50.7
LT FTRM 4 % 88.2
VEH SPEED MPH 10

The "red flag" is both long and short term fuel trims on banks 1 and 2. They were both indicating that the engine was running extremely lean when the DTC was set. This means either not enough fuel, or too much air, or a combination of both. Clogged injectors, (not likely that would happen on all cylinders at once) or low fuel pressure could be the problem. However, considering the high idle that you experienced, a more likely cause would be a vacuum leak affecting all cylinders, such as a leak around the plenum gasket, or throttle body gasket. Both of which will cause a lean mixture and high idle. It's very possible #2 injector was partially clogged causing the P0302 to set, rather than multiple cylinders. Whatever it was, it sounds like you got it handled.
