Ahhhhhhhhhhhhhh
Ok so this wannabe-stalling thing, I thought I was gonna die on the way to work this morning. I was going about 75 and my car stopped accelerating. I started pumping the gas pedal hard and fast until finally it acceleated. That was super scary, it's never done that before so I think it's getting worse. I bought a new TPS last night, I'm going to install it tonight along with an O2 sensor.
Could this be the TPS???Comment

Here is an update from robin. It is still not fixed
"We replaced the O2 sensor and attempted the TPS, but the one I bought was defective. Kyle's going to try getting them to exchange it. My car is still acting up. Dropping RPMs acting like it's going to stall when the pedal is in a certain position. It's the same position every time, and I can make it do it. If I accelerate from a stop only to get up to about 15mph, it stalls. I tried pumping the gas pedal, but it doesn't work. If I accellerate from a stop to get up to about 40mph it acts like it's going to stall - the RPMs drop and speed drops, but if I just hold my foot there it will eventually correct itself in a few seconds. Sometimes I have to pump the gas to get it to accelerate again. At higher speeds like 70 on the highway I have to pump the gas hard and a lot - it's really scary."

That kinda sounds like dead spots in the TPS

Well I Had my DVOM with me at dawgs last night and I checked robin's tps sensor through its full range. I never saw any drop in voltage when I was slowly opening up the throttle, so the tps is fine. I am buying a fuel pressure guage later today and will be bringing it to dawgs. I believe its a fuel related issue. I heard her car run, when it runs fine it has no problem, The idle is smooth, I hear no vacuum leak at all, She did replace one of her fuel injectors last year so the rest of them may not be working great. The one new one is spraying a better fuel pattern than the rest I know that for sure, But it also may be that her fuel pump is going out.

I know it may sound like a crazy question but have you considered changing the gas cap? I had a problem a couple years ago and all I needed was a new gas cap.Comment

A bad gas cap would not cause the car to stall. The evap control systems on an OBD1 car is almost useless exept for purging gas vapors from the tank to relieve pressure. Even in an OBD2 car a bad gas cap would not cause the car to stall. It would cause the "check gas cap" light to come on or if it doesn't have that light the check engine light would come on for a evap leak small meduim or large leak.
