Throwing a code 1, it seems to almost studder, and lose power after each shift. IF i give it a little more gas it comes back but it studders hard, almost to the point of stalling.

Let me know some possibilities ?

PR is good, fuel filter is good, plugs are good.. new dizzy....

 

Fuel pressure is 40psi w/ PR vacuum disconnected, which is in spec

 

code 1 is the o2 sensor in the header i messed up my wire on mine when i was pullin my trans to do my clutch and i just ignored it sayin ill fix it whenever i drove down the street it ran like doo doo as soon as i fixed it ran beautiful i am runing zdyne on my car i dont know what your set up is but all i know is if that o2 isnt function it will retard and advance the timing and really throw your car off so check in to that make shure your reading the code right to

 

It wont throw the code right away, thats why i believe it isnt any wiring issues. After about 5 minutes of driving it will throw it.

 

or you could be running rich/lean, and that could cause the o2 sensor to trip a light.

 

How would that lead back to me studdering every time i shift though ? Its almost like it just doesnt ignite when the vacuum is low
