need help
 

my 95 lt1 camaro has a bad stumble/misfire at low throttle positions such as driving on highway. The engine clears up if I give it more throttle. I ran two scans last week. Can anyone look at them and see if there are any clues?

have you tested fuel pressure yet? also pull plugs and 02 sensors to see if they is all black an fouled.

I assume there was no codes? The O2’s look funny but that could be caused by an ignition miss or injector problem or even a vacuum leak next I would put it on an oscilloscope. A good scan tool can count cylinder misses. but even that has it limits because it will not show a fueling issue or vacuum leak.

How old is the Opti?

Not sure age of opti I put new regulator pump and injectors it was flooding before that I got new plugs and wires I will install them tomorrow

Well if you had flooding issues there is a good chance your O2s are contaminate and will need replaced. We are just talking about the 2 O2s closest to the heads.
