Took the 69 Camaro out for a spin the other day. Drove it about 50 miles total. Really haven't had a chance to get out and enjoy it since I have been working on it so much adding odds and ends since I bought it for my wife in May. Mostly just up the road and testing brakes and timing.
Usually, I just take it into town to go to the store and take it home. After all, it IS my wife's car.
Anyhow, I noticed when I have it at a constant speed of about 45 or 50 mph, I hear a surging sound. Kinda like a small vibration, but not an engine surging. About at a 2 second interval. Like a moan almost. The faster I go, the shorter the interval. Then, the engine/exhaust gets louder and I no longer can here it.
I know I have an engine miss, I replaced the points and condenser and I believe it may be a bad plug. It is not that bad of a miss that the engine will spit or sputter. Just at a constant speed, you can hear it.
I was talking to one of my buddies at work and he said it may be my transmission surging. (Turbo 350)
I have had some problems that I posted earlier a few months ago that I still have not resolved yet. I still have a transmission linkage/shifter problem as well as a kickdown linkage for the transmission. I think I have it set, but there is a huge gap between Neutral and Drive and I have no Low gear. When shifter is in low, my transmission shifts into second. So I think my bushings may be bad in the horseshoe shifter.
So, other than having a lot of little problems, what is this surging/moaning I am hearing.
I replaced the gear oil so I know it isn't low, it isn't like a U-joint or a tire vibration.....
What is it?
Thanks in advance for helping me out on this one.
I know it is hard to diagnose a noise when you actually can't hear it.
