Hi,
I'm more a lurker than a poster and I try to read and search as much as I can but this time before I go any greyer than I already am I thought I would ask.
I recently installed new cam, intake, TB and I already had long tubes installed. (Car is a 2001 Trans AM LS1)
Parts are as following:
Cam - Comp XER281HR (232/234 112lsa) FAST 90 w/UMI 90mm TB and stainless long tubes.
When I first installed the LT's I tuned with AutoVe and it made a huge difference. I did the same when I installed the intake and TB and again made a big difference both in gas mileage and in performance.
Just over a couple weeks ago I installed my cam and springs, at first I had a bit of a hard time getting it to idle but I got there by following instructions posted here. I still have a little problem when starting from cold and still dies once every so often, usually when it first gets to 88c it will cut out unless I'm quick on the throttle.
Now tho when I set everything over so I can use AutoVE she wont idle at all, I can keep the car running by keeping my foot on the throttle and giving it about 4 or 5%.
Any idea where I might be going wrong? I can post my current tune and a log of idle if that's any help, at idle currently my spark is all over the place, I'm guessing that's the cam and the computer struggling to keep it going?
Thanks in advance!
Ross
