Well I was able to get this thing running today, I didn't have the thing wired completely because my fuse block from current performance was on back order, supposed to be here Wednesday but I have shoulder surgery on Thursday so I won't be working on the car for 6 weeks or so, I just had to hear it run. How satisfying is that , all those wires and the thing fires up in 3 seconds for the first time, looks like I got them right the first time. Well at least she fired right up, it was running a high idle for some reason , not sure I guess I'll find out after my surgery, can the idle be adjusted from the IAC? I think that's the idle solenoid on the throttle body, or is the comp all that can adj the idle? I didn't have my brake switch or a/c request hooked up yet, could the brake switch not hooked up yet make it idle high? Any thoughts you guys might have would be appreciated ? Other than that it seemed to run great. It was uncorked and no driveshaft ( I did have a tail shaft plug in the trans to keep the fluid in ). I didn't run it very long I just had to see if it would start up, this week I have a lot of medical stuff so I don't think I can work on it at all before Thursdays surgery,
Congrats. Must be a great feeling. I hadn't checked your motor mount prob but I guess you got that squared away also. Good luck on the surgery. I've had a couple shoulder surgery's (both rotator cuff). Really amazing how quick getting rotation back is; not strength, but rotation. A machine was sent home so I could start therapy the next morning! They don't waste any time.

Yeah I got the motor mount problem fixed. I got the autokraft pan and used the tall and narrow motor mounts, now I have plenty of Clearance under the pan. Yeah I have a full tear or the rotator cuff , and a few other things wrong in there, this all goes back to my work accident I had back in September. Been off for 5 months now, sounds like ill be off for a few more... Uggg
Jim, exactly how high was the idle RPM wise? The engines will usually high idle for about 20 -30 seconds. Part of that time is when it starts in open loop, polls the sensors, goes to closed loop, and then settles into an idle. As the temperature increases, the idle will settle out.
There is really no adjustment screw to speak of like a carb, it's all done through the PCM.....get it all hooked up and let it run for a bit, it will probably settle out. One of the main culprits of high idle on these engines is a vacuum leak at the intake.....

T,
Thanks Tom, I'm not sure what the RPMs were as my tach wasn't hooked up , but your prolly right. As I didn't let it run very long as it was open headers, it was just a little high.. Tho...I wish I could work on this but I have to go get an EKG done...

Congrats on firing the engine up that's like music to your ears! Hopefully that will inspire a quick recovery from your surgery....good luck with it!!!
If it's DBW did your motor respond to depressing the pedal? If you connect a reader I would bet that it's throwing a code saying that the connection with the TAC module has been lost.
On mine I forgot to hook up the IGN hot to the pedal and the motor idled at 1600 RPM. Connected the hot and it worked correctly.
Congrats on getting her fired up. It's a great feeling!!
