Well I got it started and the new motor was running fine for a while last night. I turned it off and started it back up. I rev'd it up a bit and put it in gear while it was on jack stands.

1st gear was good and moving. I put it in 2nd and I let the RPMS drop a bit and I got on it again and it got to about 4,500 rpms. I got on it a little more, 5,000 to be exact, and then I heard a pop. The car stumbled and shut off.

I went through and checked all the wiring, checked for leaks, checked for smoke... Nothing. I went through and checked all the electrical / ignition. I checked the new spark plugs. They were covered in gas, which was expected. The car is tuned for a full B16 setup, I now have it setup as a B16 head / B18 block and Edelbrock intake manifold and 70mm throttle body. Well I checked the plug wires. Nothing seemed off. But when I started the car again, it sounded like a Subaru WRX with exhaust.

For some reason I accidently touched the turbo manifold, and all of the runners coming from the block were hot as hell, which was expected, EXCEPT #4 I took out the spark plug and the wire. Turned the car off and saw a weak spark from the ignition for the #4 spark plug. I took out the next plug wire and put the plug into the wire and did the same thing. Same result, the plug set off a weak spark. I ran to the autopart store and bought a new set of plugs and new wires. Came home and installed them and I got the same results. Went back out today and bought a new dizzy cap and rotor and installed those and I'm getting the same results. The same "Subey" sound... Is it possible I have an injector stuck open or something. I can take out the plug and smell the gas in it.

I have no check engine lights, no bad sensors or anything.

Any help is appriciated.
