Replying to: deborahf (Nov 24, 2006 2:24 pm) the red cap is POSITIVE + and the bare or black clamp is NEGATIVE - Unbolt the positive and twist the clamp loose with a pair of pliers- then do the same to the negative clamp -, Then you have a choice- 1) at an automotive store or even walmart, buy a small chrome cylinder that is called "A battery post cleaner"- this hand-dandy device has wire brushes inside it, and can clean the battery post, AND, when the device is taken apart, it has another brush than can clean the opposite end the battery clamps-This device is used by a twisting motion- If you want you can clean the bluish powder off with a small hand wire brush and then shoe-shine the battery post with a piece of sand paper, and do the same to the battery cable clamp. A word of caution- do not get the blue-white battery post powder on your clothes or near your eyes- it is caustic. It canslowly destroy you clothes like battery acid. Another way is to finalize the cleaning by hand, then washing with a wet rag, the wash with baking soda and water- then washing and drying- re-assemble and presto ! all done. IT is NOT difficult, and should take less than 30 minutes from start to finish. Good luck !

1994 Geo Metro Automatic Transmission Our Geo Metro has recently begun to occasionally lurch forward when accelerating from a dead stop. Sometimes this happens when it has been parked for a while or overnight, but it also happens at traffic lights, stop signs, etc., anywhere it has come to a full stop. It lurches once, then moves forward as it should. There is no problem with changing gears or acceleration after the first "jump." Also, this lurching is the only symptom of a possible transmission problem -- there is no noise, gear change difficulty or hesitation -- nothing. Our Geo has a little over 83k miles on it, and it has been regularly serviced, including a transmission fluid check. However, there are two chronic conditions worth a mention, but I don't know if they are related to the current lurching problem: Our Geo has always had very little acceleration power on "take-off," but once it's going, it runs great. This lack of power issue has been repeatedly addressed over the years, but our mechanic has yet to pinpoint the cause -- we've learned to live with it, and we don't pull out into traffic until it's clear a looooong way down the road. Also, wet weather seems to cause our Geo to sputter and complain -- hesitation and very little acceleration power. However, once the engine has run for a while or after the sun comes out, this disappears. This is another issue that's never been resolved, and it has been a bit of a pain since we live in Florida where it's wet most of the summer. As to the lurching, we had our mechanic drive the Geo, and since he's not a transmission expert, he hesitated to make any diagnosis. He just advised us to have the transmission looked over. We know nothing about transmissions, and we've heard all the horror stories about bad mechanics cheating people like us. So, understandably, we're nervous about taking the Geo in for a diagnostic on the transmission. If anyone can suggest what we need to be aware of or if anyone has another idea what the problem might be, please post. This is our only car, and it has to last a while longer. Thanks...

You maybe correct, the tranny is of suspect. The only other thing I can think of is bad CV joints. You don;t mention how many miles on the car- for what it's worth, my 1995, with 116,000 miles on it has the lurch problem you describe, but it just started it recently. But it has a great pick up and go- no lack of power. Now my 1997 Geo has the lack of power issue, but not the lurching (yet) both of mine are automatic transmissions.(I assume yours is too) Well, the only thing I can suggest is a good tranny shop- like AAMCO . good luck-

Replying to: annablume (Nov 30, 2006 3:38 am) Second - please check the connection between the accelerator cable to the trouthle body. If you have very little clearence between the set srew and the "cam" plate, which is attached to the acceleratore cable - you will need to lubricate the shaft in the "carburator" ( trouthle body). Check also the spring attached to the camplate is not damaged.  Let me know.

Replying to: p10leadman (Nov 30, 2006 7:23 am) Our Geo has about 83000 miles on it, and it's never been driven hard or for very long distances - we use it for around town mostly. And yes, our Geo is an automatic transmission. I looked up CV joints today, and apparently a symptom of a bad CV joint is a clicking sound on turns. As I described in my first post, there is no noise whatsoever when the Geo lurches or when it turns. However, we'll have the CV joints checked. I guess we'll also be seeing the AAMCO guy too.

Replying to: pipeman (Nov 30, 2006 7:56 am) The lurching happens mostly when the engine is cold, but sometimes it will do it when it's hot. For example, if we come to a full stop at a stop sign, then accelerate, it will lurch or jump, then it's okay. We'll have the connection and spring checked as you suggested. What you've described sounds very probable, given the Geo's performance.  Thanks again...

Thanks to all! I had a tune-up done and my car seems to be starting with no problem now. Even in the rain. Also, I am driving below half a tank of gas because of the gas leak. Can't do the gas tank repair yet. Keep your fingers crossed. Deborah |
