A little background: my 95 Ford Escort 1.9 has 123k miles on it. I just did an oil change. I've done Air Filter, Fuel Filter, Plugs, Wires, cleaned the coil pack, cleaned the EGR, cleaned connectors to just about everything. Cleaned the IACV a little. I've looked for some vacuum leaks, replaced the PCV elbow. Checked the valve (was clean, free moving, might still replace as it seems "too free"). I've also ran SeaFoam a few times with good results. It took away a lot of hesitation and struggling the car had when I got it. But unfortunately never fixed this problem! What happens is while idling, hot or cold (although it seems to take longer cold), my car will stall at random. It usually happens when I leave it in the driveway to warm up, or at long stop lights. It takes approximately a minute. The perplexing thing is that sometimes it will start coughing and shaking and die. Other times it will just turn off without warning. One thing that used to keep it from stalling was running the A/C compressor. If I had the A/C or Defrost on, the car wouldn't stall. Oddly enough, this recently stopped helping. This problem has been going on since I got the car at 109k. The above maintenance was performed in hopes that it would fix it, but of course never did....haha What are some other reasons it'd be doing this to me?
