ok so I need some opinions...
I was getting off the interstate, and got into traffic. I was starting out in first gear when I heard a pop...like a backfire. So now, when im starting out in first, or if i put the car into 6th, or under heavy acceleration, the car sputters. I have shorties on the car, 81k on the motor..not much else...Any thoughts?
I've heard people say maybe exhaust manifold gasket, bad patch of gas, or a spark plug. oh, and here's the kicker, I'm not throwing any codes....

I'd try some plugs and wires. I've had several GM plug wires go bad on a few cars I've owned before 30k. Also i've test driven a few TA's and formula's that needed new plugs with less miles than you have. I changed my plugs and wires at 65k just to make sure. MSD wires and NGK plugs. Got a package deal from ws6store.com. Lot cheaper than local.

Back in 03' When I had my firebird GM had a recall on both T/A's and FB's 95 and up for the stock plate that the coil packs sit on. The plate would cause a short causing your coil packs, plugs and wires to blow apart. The first signs were of this happening were when starting out in first, or under heavy acceleration, the car sputters. Then next thing you know wires are blowing apart, then you start having mis-fires....After several trips to several different shops trying to get my computer read looking to find out WTF was going on, I got sent to Iraq, throughtout the year I kept up my research...Took me a year to track down what was the root cause...GM released a recall msg for it , OC I was passed the time limit so I bought the plate, replaced it and my FB came back to life.. It turns out the that stock plate needs to be change every 65k to 75k miles... Not sure if this helps....just food for thought.....
