Had Autozone pull the code and it was something with the flow and an EGR code. Replaced the EGR valve and it still idles poorly and even dies in the middle of a turn after slowing down from higher speeds.
Any ideas what to check next? Autozone wasn't sure and I don't have a clue.
Thanks in advance,

It sound like your EGR is stuck "open" This will cause it to die or run rough at low rpm. The EGR should only allow exh. to flow back into the intake at "high" rpm. If it gets "stuck open" or the vac. tells it to open at the wrong time (low rpm) then your motor will do just what you said. Check it out & see if the ERG system is getting hot at idle. Should be cold if closed.

Curious.
My '93 16v occasionally dies when the accellerator is pressed when the light traffic turns green or at other similar situations. Is this similar to what is happening to you? Because it's the older OBDI, I am not sure exactly how to get the codes read...
-
Ack,
No, mine dies after letting off the gas and pushing the break to come to a stop (in the middle of a turn no less). Try Autozone for the codes. They always ask me what year mine is. I'm not sure if that is because they don't do the OBDI or just need to know which to bring outside.
ToyYoda,
I'll check that out by feeling the valve tomorrow. It hasn't died in a few days now but the rpms drop drastically at a stand still like it wants to die. Is there more to the EGR system than just the valve? I know there are some hoses (vac?) that lead to another part up on top of the motor. Could that be bad and if so how could I tell?
Thanks much,
Jerry

There is a valve controlled by the ECU that switches the vacuum through to the EGR. Usually mounted near the front of the block

Hey, im new. I have the same problem with a very low idle when coming to a stop. Once i get stopped though, the idle bounces back up to where it should be. When it starts to die it somehow idles pretty much down on the tach peg.
Ive taken off the egr valve, cleaned that filter off, still didnt do anything.
Took off isc valve, blew it out, put a new gasket on it, still does it.
Some time this week im gonna put in a new pcv, it looks kinda loose in the valve cover.
Supposedly someone had the same problem near me and took it to a couple dealerships and none of them could figure out what the problem was.
BTW, i drive a 93 sidekick 4dr.

  I had the exact trouble on my 95. There is a screw (Idle Air Adjustmt Screw??) near the battery under a rubber cap. I turned this screw 1/4 turn, problem solved! Only thing is, I can't remember if it was clockwise or counterclockwise! Here's Wildweasel's pic of the screw: http://home.comcast.net/~icepoint/P1010014.jpg

but it only starts to die sometimes, and there is no rhyme or reason to it. Itll idle fine most of the time, but sometimes itll almost die coming to a stop, then idle back up to where it should idle once i have fully stopped.
I dont know if its just a coincidence, but it doesnt seem to do it as much on a full tank of gas, i dunno.
-
i have the same problem. engine dies when i come to a stop sign. seems to only happen when the engine is cold.
-
Bump,
Did anyone fix this? other than the idle screw? I am wondering why I would need to adjust that if it is set their from the factory. It seems like something else has changed and we are compenstiong for potentially another problem. Not saying the screw method won't work, In fact I am going to try it cause stallig while I push in the clutch and come to a stop sucks.
I had a similar issue with my Dodge ram and it was the speed sensor... Anyone know where that is on these things? Is is in the dash or on the T-case?
-
Yes the vss is in your speedo, mine is a small reed switch next to a small round disk with a magnet inside it, the disk is inline with the speedo cable, yes it will cause it to stall at a light and cause bad gas mileage when they go!

If it only happens when its cold then it could be the temperature sensor.

this fix will solve all your problems.
this idle screw, over the years, backs out from the vibration of the motor ;)
i think you turn it clockwise

Another thing to check is the tube that goes from the EGR to the manifold (steel tube).
Mine was clogged at the manifold end with carbon. Take it off completely (4 10mm bolts), and run a wire through it. Also clear the port in the manifold because it may be plugged too. Unblocking the tube and port fixed this problem on my '96 and cleared the EGR code after about 30 miles of driving.

Mine is doing the same thing right now. The screw in the back did keep it from stalling, but the idle still goes up & down 1200 rpm - 1900. I think the problem is the timing advance. Is there a way to lock it out & just set it at 35 degs?
Does anyone know which wire on the distributor or VSS controls the advance?

There isn't a single wire that controls the advance. Its calculated by the ECU based on information on RPM, manifold pressure (unless you have a seperate vacuum advance), water temperature and air temperature. On OBDI models you can put a jumper across the diagnostic terminal to fix the ignition timing.
-
I was looking the FSM. A fault with the idle switch does not set the Check Engine Light, you have to pull the codes. I also know that on some Mitsubishi ECUs the same applies to the VSS, however the FSM indicates that this is not the case on a Zuk.

That's the info I needed - thx...Can you tell me which wire it is? I have a '95 16 valve "California" model Geo Tracker, vin code 6.

FYI - I figured out the engine surge problem. Their was a vac leak at the EGR valve. I replaced the gasket & torqued it down, no more surge.

i am having the same sort of problem with my 97 1.8L sport. it idles pretty slow and rough for a few seconds at stop. it is a auto tranny. i looked for the idle air adjustment screw but couldn't find it.
any body know how to solve the problem ont he 1.8L?
thanks

whats the fix for this ont eh 1.8L
mine is still doing it. is there a idle adjust screw ont eh 1.8?
