2000 ZX2 Occassional Stalling

I'm having an issue similar to what's going on in this post:
http://www.fordforums.com/f63/2000-z...unning-168375/

My ZX2 has apx 155,000 miles on it. About 2-3 years ago I was having a problem with the car stalling (engine would just cut off) pretty much every time I came to a stop or close to a stop. Turned out there was a hole in one of the vacuum hoses. This current stalling issue is very similar to what was happening back then.

Car starts up fine, when I slow down/down shift to turn or if I stop at a light/stop sign the engine just cuts off. There's no shutter, no roughness, no indication that anything is about to happen. In the case of slowing down to go into a turn, the only way I know it's stalled is the power steering is gone and the dash gauge lights come on. I turn the key and it starts right back up again. Nothing unusual while driving.

The stalling seems completely random. It first happened a little over a month ago, coming home from running errands I slowed down to pull into the driveway and the car just shut off. Then again the next morning about 5 minutes into my drive to work, slowed down to turn onto another road and the engine cut off. My husband checked the vacuum hoses (or hose) and said there was a little bit of dry rot, cut the dry rotted end off the hose and reattached. This seemed to fix the problem until this morning. The engine cut off 3 times this morning, all when slowing to turn or stopped at an intersection, all within the first 15 minutes of commute.

Around the time the engine cutting off thing started a little over a month ago, I noticed that the RPM's were quite low while idling. Like when I'm stopped at a light or stop sign, the RPM's will drop to about the .5 mark (used to idle around 1). It doesn't stall out when it drops to .5 though, just drops down for a couple seconds then will slowly creep back up to 1.

Shortly before the stalling/low idle RPM's started, my air conditioning went out. I can't imagine these issues could be related but I figured I'd through that one out there just in case. I had a broken tie rod and something-or-other joint, then after that was fixed the air conditioning didn't work (literally one day it was producing super chilly air, the next day the cold vent air isn't even cold and the air conditioning is warmer than the cold vent).

To summarize (since this is way too long and probably has unnecessary details):

- Apx 155,000 miles/Manual Transmission
- Engine randomly cuts off while slowing to turn, or stopping
- Idle RPM's around .5 instead of normal 1 (has never stalled late enough in a stop for me to notice RPM's - stall at stop or slow is usually within seconds of downshifting and breaking)
- No "Check Engine Light", no code

And not sure if these things are symptoms of this issue:
- A/C doesn't work
- Lights inside dash and on the vent/fan control panel are dim or not working at all.

Any guesses? (sorry about the question overload!)

Re: 2000 ZX2 Occassional Stalling

With the stalling, try what I recommended in the earlier post. "Try cleaning the MAF and IAC to see if that helps. There's a special MAF cleaner for the MAF."

With the A/C problem, does the compressor come on? It's probably nrelated to the tie rod replacement. There are switches that control the compressor and one could be bad or came loose.

The control lights are probably a burnt out bulb in the control head.

Welcome to the forums.

Thanks for the suggestions on the stalling, I'll get on those ASAP.

With the a/c - is "nrelated" unrelated? I vaguely remember reading something about something related to the a/c being located somewhere near the passenger side wheel, which happens to be the side that had the tie rod/something-or-other joint replaced.

Re: 2000 ZX2 Occassional Stalling

Yeah, it Could be nrelated "Unrelated". I didn't check my spelling. That is the area and it could be something they hit, that's why I wrote "Probably". Beimg in the business, I've seen things happen after working on a car, where it had nothing to do with it. And sometimes it did. I replaced a water pump on an Olds, (1968) a long time ago, and the radio quit working. The customer thought I knocked something loose in the engine compartment.

Re: 2000 ZX2 Occassional Stalling

It's very likely that the a/c problem is a bad relay inside the CCRM (constant control relay module). Very common problem on the Escorts. The CCRM is located on the drivers side of the engine compartment underneath the air intake tube. There's also a low pressure switch for the a/c system that will prevent the compressor from kicking on if the freon is low and there's a cycling switch which cycles the compressor on and off. If you find out it is the CCRM let me know, I have some of different part numbers for sale and if that is the problem I might be able to fix you up. A new unit is between $200-$300. I am asking $60 plus shipping and a $15 refundable core charge for a used unit.
