I had this problem start almost 20K ago. Start up the car, car immediately stalls. Start it up again, stalls. This try I try giving it a little gas and it's fine, but as I drive off each time I depress the clutch the RPMs fall to zero. The car doesn't drive erratic and as long as I am NOT depressing the clutch all seems normal--it's once the clutch is pushed in that the car stalls on me, no matter the speed I was first going.

The worst part about this problem is that it will haunt me for a week or so, then completely disappear--leading me to think that whatever I do to eliminate the problem (clean the throttle body, clean my air filter, etc.) is working...then the problem comes up again months later, randomly.

Any ideas? Or is anyone familiar with this problem?

I am having the same problem with my 95 GS. It has the same problem with starting and pressing in the clutch but sometimes when I press the clutch in while coming up to a light, the RPM's don't fall when other times they fall to zero. I also can't let it idle without dying on me. It also surges while driving and my battery light and check engine light on my dash flash for no apparent reason. So far I have replaced the battery, spark plugs, plug wires, alternator, and ignition coil. I have read somewhere that the fuel pump could cause the car to do this. If the fuel pump doesn't fix it then it looks like I may be buying a new ECM.

I had that exact same problem 1 time and it did it for 10 min. After that it hasnt done it. If anyone can help i would appreciate it.

Check all your vacuum lines, spark plugs, fuel filter, EGR.. It's either too much air or not enough with most idle problems.

I posted this awhile back but will repost it again. I hope this helps. LOTS to people let me know that THIS WAS thier problem.

Hello again.I am adding to this to let everyone know that those who clean their engine a lot are the ones who will PROBABLY notice this the most. The moisture and cleaning agents get in past the NO O-RING area and affect the TPS. I am not telling you to NOT clean the engine. Just be aware that if you have bad idle a few days after, you know what MAY be the problem.


Erratic Idle -Service Slant

I have just received my latest Motor's Book for February and I thought the list would be very interested in a few articles in it. I am sending this because I know for a fact that there is a problem here. I have replaced a TPS on both My Talon and on my Brother in law's Neon ,both in the past 3 days. Both have the Chrysler 2.0 L engine (mine the DOHC and the Neon has the SOHC). This is for the 1995/96 NT Talon ESi and base Eclipse. Also ALL 95/96 Neons.
ERRATIC IDLE
Some 1995-96 Eclipse models built before 11/1/95 with the 2 liter DOHC 4 banger may suffer from an erratic idle, a loss of power and an illuminated MIL.(Engine Light). You may find a DTC26 (or 24 or 25) which is for low throttle position sensor voltage stored in the memory. And if you do actually find a bad TPS, check the throttle bore part number first. It's embossed right up on top so it shouldn't be hard to see.
If the part number is M04669032, your looking at a throttle bore that was manufactured without a TPS O-ring seal to prevent moisture contamination. So that throttle bore has to go. Install a fresh and updated version (Part No M04669860) with a new gasket (Part No M04669034). Note that the new bore comes with a fresh TPS already installed, so you don't have to worry about ordering one seperately.
If the throttle bore on the car is the correct updated version, however you'll have to order up a new TPS and O-ring (Part No M04874430) to complete the repair. Before installing the new TPS with its new screws, slightly lubricate the O-RING with some vegetable oil and insert it into the throttle bore grove. Don't stick the O-ring over the end of the TPS; it may get pinched when you tighten down the sensor.
NOTE: Mitsubishi warns NOT to coat the O-ring with engine oil, because it wont lubricate properly.

I hope this helps anyone who has or will have any problem. As I said, I have had the problem. You can buy the TPS (with the O-Ring) at Carquest. They may be hard to find but can be ordered. It is a STANDARD part and is part # EC TH141. This is the upgraded version.
