Hi I have a 92 beretta. I just got it a week ago. It had died on me once on the way home. Now every time I go to stop I have to keep my foot on the gas. If I drive over 40 mph and go to stop holding my foot on the gas dont work. It starts getting really slugish than dies. It starts right back up after it dies. Once it starts back up I have to keep the rpms around 3000 and shift from nutral to drive so that it wont die again. It didnt start dying all the time till after I unhooked the battery and took the alternator off to get to the blower motor.

Has the check engine light come on? Have you checked for vacuum leaks?

Let me know.

Yeah the check engine light comes on after it has been running for a little while. I cant afford to take it in to have it scanned to see what the codes are. It has the OBD1 port so I used a paper clip to get the codes and it said the TPS high and low was bad so I replaced the TPS. Its still doing it though. I also noticed today that the car is using an enormous amount of fuel now. I had to remove the IAC to get to the TPS and I acidently pushed the plunger in a little bit on the IAC. I didnt think it would matter so I put it back on and got everything together and started the car. Once it started the rpms went straight to 3500 and stayed there. No mater if I gave it gas or not it didnt drop. So I took the IAC back off and pulled the plunger back out a little and it ran fine for a day. Now its back to the samething. Would a bad IAC cause all my problems? If so is there a cheap way I can test it so that im not dropping more money on a part that I dont need? As for the vacuum leaks ive looked over everything under the hood and have found nothing that is not hooked up or unhooked for that matter. I was also told that I could be my alternator. Could that be causing it to just die at stops? I wouldnt thing that would cause it to use the amount of gas that it uses though.
