Alright, so on Saturday I wasted my time and money going to the track ($20 for gas, $43 for racing plus a spectator) to find out that the car STILL isn't working right. First run was a 16.8 and the second was a 16.5 Last year at this time the car was running 15.59. Since then the only thing I have changed is the ICU (Ignition Control Unit) because the car had no power and sounded like a freakin' go-kart (not the shifter kind).

After getting a used ICU off of Kyle (Rawkfist) I installed it and the car was seemingly back to normal. I took the car to the track about a month ago and ran a 16.5 I can't say for sure this is the problem, but its either this unit or a fuel issue. When I initially got the part I didn't know that auto and manual transmissions made a difference with this, but I was informed by the dealer that it did. When I spoke to Kyle about this he said...

... that is the ICM Zach. And that did come off an auto engine, there was a flex plate attached to the crank when we shoved it into the car.

Another thing that began to show itself and why I left GLD after only 2 hours was that I turned off the trans torque management. When I read it to the computer the car didn't want to idle. Seeing that this wasn't going to work I returned it to stock where it again didn't want to idle. In order to get out of there I held down the gas just enough to keep the RPMs around 1,000 while stopped. If I didn't do that when I came close to stopping the car would shut off.

Now that I'm home something else just came up...the car now runs decent (power not all there obviously) but when I start the car it idles at 1,000 RPM for about 10 seconds, then jumps between 750 and 1250 RPMs for another 5 seconds, then finally settles at 600 RMP, but still waivers a little. If anyone has an idea I am all ears! Either way, I'll still be going to the Dells...probably just slightly under powered.

hehe sounds like the fuel pump needs to be replaced

dont jump to conclusions..... rember all engens need 3 things to run..
Fuel
Compression
Spark.

every thing is "add on's" could be a crank sensor, bad PCM, bad cam senser, bad O2 ... list goes on......

start diag, and go from there..... whats fuel presher at?
MV from B1S1 O2?
Fuel trim?
Spark avd?

give us a call this weekend... either me or tom, or both.

then you can help tow the GTZ

I see two things wrong with this.....

1. Baby shower happens BEFORE the kid is born

2. Baby showers are for the LADIES



now back to the car...... I no longer work for GM (and Chris does, but didnt post any info on this)...... but I just cant see the ICM having to much to do with the Auto vs 5 speed issue. If you are throwing codes (thought I read this in the other post) for Auto trans issues, I'd lean towards the trans is the fault, or the PCM itself (either physicaly or programming)

Send me your HPT file, we have a license for the '02's (well, cavies at least) so we should be able to play with it.

Alright...I'll just send all of them that I have.

To dispute your points...

1. Kid is still cooking
2. I still get stuck helping setup

... i guess i could have cheeked part numbers for the ICM's.....

02-07 L61, all makes, all modles use Part Number 12580215 ICM.

So what are you guys up to Sunday or Monday? Maybe you can at least take a look at the car, or even better have enough time to install the parts.

idk, I have a wedding on Sunday, and might be out of town on Monday. You can see if Tom can have his balls back for a few hours, he might be able to look at it for you.

FAWK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!

Its okayk, I too know that feeling. Just let me know if you have some time.

Well, this may just be part of the reason the car runs slow, but when it gets started it'll idle at 1k for about 5 minutes and smells like gas pretty bad.

Ended up being the damn gas cap. Not sure if all the power has returned, but all the tunes work except Tom's which has never worked. Back to where it all began.
