won't idle, cam position sensor?
#32
Well just pulled everything apart and the timing marks seem to line up and the cam is in there snug and isn't loose. So any suggestions before I put it all back together again?

Got'er runnin again and no change so I did some searchin and people suggested upping the throttle stop screw and if that don't work, the blade screw is pretty much flush on the bottom going up. I drilled the blade and I stopped at 13/64 and its still hit and miss. The colder it is the better it will hold an idle. Should I keep drilling?

you have to turn how much the injectors are told to flow, if you have 28lb/hr injectors flowing at 98% and you install bigger injectors, they will be told to flow at 98% when maybe they should only be flowing at 87% or something. any custom tune should be able to take care of this. HPT, LS1 edit, EFI live etc

I have a flow calculator all I need is to find out what my origional fuel pressure is what the new pressure is ( i'm assuming the same as I never changed?) and enter the lb rating of the new injector (31) and it'll give me the new flow rate. Just waitin on the new laptop to download the newest version as I am still runnin the 1.6 with a 25 foot cable on the home comp. Just tryin to find out what I need to do then to git-r-dun.

Yeah I thought of that too, so I tore it all apart and had a mechanic friend come over and double check and it was right.
