Just recently the other day i would start my car and it would run fine, drive it for a minute and then it just start bogging and idleing very rough.

I switched out my plugs and does the same thing?
Wondering if either a sensor is bad...
Have a bad tank of fuel....
Plug wires are shot....
I havent had it scanned yet, cause i cant actually drive the car long enough before it runs crappy?
It ran just fine all the other times, and then i get ready to go out one more time, and it starts running crappy??

Sounds like something that doesn't act up until the car goes into closed loop. Oxygen sensors are a good possibility, but you need to have the car scanned to verify that.

I would say that's your problem right there. Why are you trying to drive it with no O2 sensors?

^^ my harness is cut were the O2 sensors would be, so i have to rewire the sensors, plus i have to redo my exhaust or wled in a bung so the sensor can be placed in the exhaust. Its been running fine for the last couple months of so, but now its starting to act weird like this. Im going to try and get everything rewired back up.

Just a guess but have you checked the plugs? Maybe you fouled them out running it open loop so much? The PCM Adds alot of fuel during open loop IIRC

Yes, as stated in the 1st post i did change my plugs.
i did end up wireing up an O2 sensor and reflashed my PCM and did the same thing?

So i checked my fuel pressure.... And i have very good pressure. Between 60-65 psi ( i have the corvette reg/filter.

So i released all the fuel in the fuel rails, and primed it again, and then released the fuel again, primed it back up started it, and now it runs fine?? Possably i have some bad fuel then? I hooked up my wide band and it does run slightly rich but its upper 13s lower 14s.
