Something strange is happening please help...

[SHO SPD]

Well my SHO is acting a little funny, I dont know what the problem could be. Heres whats happening:

when I am at low RPM's in 1st 2nd or third I hear a pop 1 time sounds like its from under the dash by the exhaust (its not loud, and it only happens sometimes) and it feels like the car is struggling for power, it kinda lags and lunges, but when I am at higher RPMs its fine....please help

Holy cow, I've got the same thing happening! I really want to find out what it is, it almost sounds like a mis fire or something. Anyone with any knowledge please help

Does this happen regularly? Off hand it sounds like exhaust backfire. That means there is a leak somewhere. I would suggest getting under the car while it's running to see if you can feel it leaking. Check the cats/catback seal, the y-pipe to exhaust manifold connection, or for holes in pipes or mufflers. Also when I put my Sho Shop y-pipe on I had 2 leaks with backfiring near the cats and had to fix it with a welder.

94ShoATX: nope this is my only post about this.

It does not happen all the time, and when it does its minimal, I am just curious. Its not bad enough to even worry about because the car runs perfectly fine.

Sounds like you may be having a spark crossfire or misfire. You should check at least the front three plug wells for oil, but I bet your plug wires are not what they used to be.

Scott, what's a good way to test wires? Is misting water in there at night a feasable thing, or is that a wive's tale? I was talking to shotime last night about the possibility of either a stuck valve, worn cam, or something of that nature. I'm pretty worried that it is going to cause damage. It happens rarely and I cringe when it does it.

I dont have any oil in any of my plug wells front or rear, its probably the wires, I am getting new ones before I sell it, so maybe thats it.
