Help after rebuild 7mgte

yeah you cam sensor need to be adjusted via a timing light. you can guess at it (adjust it while engine is running till it runs smooth) but for the 50 bucks for a timing light you know for sure.

I'm getting ready to try it in a few, I did try to do it by ear but didn't do anything. I also bought some ngk's so I'm gonna put those in first.

I just had my motor rebuild and the guys that build it had my distributor off a tooth or two and I had trouble getting it fire up but it did start and ran shitty had to pull out the distributor and fix it know it runs great and get a timing light it makes it so much easier To tune

Was that on a 7mge, mine is a gte. Well I changed the spark plugs and checked the timing and it ran a little better but it still sounds like its misfiring. I found one air leak on the back side of the intake. It is a steel hose that bolts to the intake. Its a very small air leak so I don't think it would be causing it to idle down to 400 rpm's and killing it. I really wish I could figure this out.

Having not experienced the results first hand, have you checked your crank is not 180 degrees out from your cams?
I would doubt the engine would start, however, if it did???

It shouldn't, I've made that mistake before. Before anything, FIX YOUR AIR LEAK. Also, did you set your timing with the jumper wire in the diagnostic box? If you didn't, your timing will still not be properly set.
