Default Coughing, Gagging, Gasping...shes DYING!

I think I'm answering my own question here, but I'm posting for conformity reasons.

Recently my 94 SSE has been feeling like I hit imaginary bumps as if shes gasping for gas. I conclude that its the o2 sensor because, if memory serves me right, N/A bonnies use heated o2 sensors where this symptom would only occur when the car warms up....no?

Also when I hammer it I can feel it hesitating and as it cools down to normal operating temps I still feel it acting funny.

So how much are replacement o2 sensors?

Like $36 or somthing close to that if you deal with Napa stores. i just had one priced the other day, just cant remember the exact amount. but i know im in need of one also, so when the cars out of the shop...im getting one. Car Quest was almost $5 more if memory serves me correct.

for my info allmachtige is your oil pressure a wee bit low once its starts gasping and when its cooled down does it sit back where it should?

Hmm...I'll check on the oil pressure. What could cause such a problem otherwise?

Yeah, my buddy who is helping me tune for the track says once I start going to the races every week I'll go through o2 sensors left and right. I'm gonna go ahead and replace it anyway and see if this is really the problem.

Don't wanna sound like a broken record here, but buy ONLY AC Delco O2 sensors, even if they are more expensive. You've heard it alot before. Even Jr and I have been bitten by that snake.
