Question about 2002 Chevrolet TrailBlazer

Open Question

What can cause a 2002 chevy trailblazer to shake really bad when put in drive or reverse. There is no check engine light or anything showing a code just really bad shaking. I checked the transmission fluid which is full along with the oil. It started about a week ago but has gotten really bad to the point where its undriveable.

SOURCE: check engine light on, car shakes while in reverse, stalls ...

You need a code scanner hooked up to find out what is causing the light ot come on. Some auto part stores can do that. Once the code is retrieved, they can tell you what sensor is causing it.

I have a 2000 Mercury Mountaineer that runs perfect while in park or while driving. When stopped or put in reverse it shakes and stalls.


Is the check engine light on? Mountaineers are bad about developing vacuum leaks which will lean the engine out and cause it to stumble at idle while in gear. Check for p0171 and p0174 codes.

Car shakes in reverse and engine light is blinking, gears will not change gets stuck in 2nd or 3rd gear


When the check engine light flashes it means DONT RUN IT or you will damage the engine. There are codes that your mechanic pulled from the computer, WHAT ARE THOSE CODES?

2002 nissan altima started shaking and check engine light came on


Blinking means that the problem is so bad that it can damage the engine if you drive it. You need to get a code reader from an autoparts store and read the codes to see what the issue is.

I have a 1994 Chevy S10 Blazer bad reverse


The odds of two different transmissions having the same problem in reverse is astronomical. I think your problem is in the differential. Also check for the proper fluids and additives in the differential.

1999 New Beetle. PLEASE HELP! SHAKES REALLY BAD!


A shake with the engine running (known in the vernacular as a "shimmy") can be caused by several things. In this case, since it's at idle, I'd wager either a.) timing went off, which in an EC (electronic control) vehicle means you should be asking "why me?" or b.) could be a miss. Chances are, whatever the problem, that check engine code that got tripped will tell you what happened. It might be a simple thing like a sensor malfunctioned and now is telling the engine to fire wrong, dwell wrong, too much gas...etc, or it might be something went seriously wrong (broken engine mount, bad distributor...etc). Either way, get that code read and you should be able to get back on the road.
