my car idles at about 400 rpm's and wont go any higher than that and dies after 5 min. do any of you guys no what the problem is. all sensors are hooked up correctly and workin accordin to the sensor we use to test it w/

the engine is rebuilt, it ran fine at the shop (it overheated badly entire engine needed to be redone) then me and my uncle took it to his house and rebuilt it. the engine is installed but it has the problem mentioned above.

My mods are CAI, cc306, flowmaster, bored out a little more, oversized pistons, b&m ripper shifter. in the spring the flow is goin for borla and pro 5.0 for b&m. we checked all the fuses and they were fine but when we crank on the starter the o2 sensor wiring was burnin but we fixed that problem and still no startin.

 

with the overbore and the 306 it my need a pcm tune.
