Got the car running.... again, but now have a new problem (what's new). So I jumped on it in 1st gear, and rpm's shot up and car made a loud *** backfire and then the motor shut off...

I thought for sure that I blew it up, I was coasting down a hill at this point so I figured what the **** was that, might as well try to see what damage is done, turn the key, fired right up, no weird noises.

Put the car away, checked oil nothing looks bad and it's full, nothing is leaking OP is 50psi at idle. So I went and got a bacon burger came back and wanted to try and take it out again... This time I slowly rev'd it up so I could find out where the hell it was happening 1,2,3,4 rpm are ok, started to "pop" then 4750rpm POW! motor shuts off.

Car runs normal, no knocks at idle... Any ideas or **** to check?

Anyone want a H/C/I 347 Formula? haha

A backfire is nothng more than unburned fuel dumping into your exhaust. Since your exhaust is hot, the fuel ignites inside your exhaust and causes the backfire. So basically, one or moer of your cylinders is not burning the fuel and it is getting spat into the exhaust.

So, you should check your plugs, plug wires, and ingnition components such as coil packs, wiring, etc.

Check your cam sensor. Make sure it is plugged in. If you have converted to a LS2 style sensor you will have to swap 2 of the 3 wires (A&C).Are you running your maf?
