No prob starting, idles fine... there's a point on the gas pedal where I'll feel it start to lose power, then the 'howling' sound eminating from the carb barrels...changed the fuel pump about 2 months ago...could it be related? Any help greatly appreciated!
I've been told that it could be catalytic converter?

Ok... it's funny because I just looked up 'signs of converter failure' and that's what they suggested, too. Much appreciated!

Disconnected the front 02 sensor....still getting the groan when I got that spot... that's only in D, stationary. I'm going for a spin around the block to see what it does under a load.

 

Try removing the front O2 sensor from the exhaust pipe. See if it runs any better.

 

I can feel a slight bit more power, but still doggin it.

 

Recheck fuel pressure.

Whens the last time it had a tuneup? Does the Check engine lite start flashing at you when it starts doggin?

 

Didn't have a check engine light until I disconnected the sensor... I changed the plugs when I did the fuel pump... about 2 months ago. It was running strong...the new pump really made a difference...it sounds like the carb is sucking for air...idles and starts no problem... I'm going to try to record the noise and post it if possible.. thanks again.

 

And light does not flash.

 

Think I would try and test the TPS as well.....
