1992 Chevy Lumina 6 cyl Front Wheel Drive Automatic 101000 miles
I recently puchased this vechile for a back-and-forth between work car. It has right over 100,000 miles, and it ran great when I bought it. Now that it's getting cold, some of these problems are starting to show their ugly face. When I first start it, it tends to idle high (1000-2000 RPM) while in park. When in any drive gear or reverse, it drops down to normal but idles very rough. When I begin moving, the sound of the car changes dramatically. The engine/exhaust sounds a lot lower and deeper than normal, and the car loses quite a bit of its power. Once I finally get up to normal highway speeds, upon entering final gear (or overdrive, I'm not sure which), t feels like the transaxle is starting to vibrate and I have to let go of the gas and then push it back down for it to stop vibrating, but then it goes back into doing the vibrating after a few seconds. So, while I'm driving, I have to constantly let off the gas, reapply, let off the gas, etc. Warming the car up does not make any difference. The majority of the time I drive, it does this. It randomly goes away while I'm driving, too. The exhaust and engine will sound like it's supposed to, but then minutes later both sounds change and driving becomes sluggish again. If I come to a stop at a stop light, the car will idle rough and upon take off, if I give it too much gas, the transaxle will shift rather hard. Hope this is enough information!
have the same problem?
