Question about 2001 Oldsmobile Alero

1 Answer

Alero shakes when idling

My car shakes when idling, not while in park or neutral. Had plugs changed 2yrs ago. Took it to a shop today, and they don't know what is wrong! Say could be a "worn out motor" or possibly a transmission problem. 2 motor mounts changed within the last 5yrs.

I would get the car in to a mechanic right away. Sounds like the converter might be plugged. This has been known to cause car fires.

SOURCE: 2002 Alero shifting hard

I have a 1999 Oldsmobile Alero and my car was running rough and stalling. Also when the car was shifting, it was making a "thud" sound. My service engine light was on, so I took it to Autozone to run their diagnostic tool. It came back with code P0108 and they advised me to check my vacuum hoses as a possible solution. I looked and found that my air hose running from my throttle body to my map sensor was disconnected. I reconnected the hose and the engine ran normally and didn't make any "thud" sound when shifting. My car is back to normal. So check your hoses. If its still running rough, you may need to replace your map sensor.

SOURCE: i have a 2000 alero that idles rough and smells like old gas

I, too, have a 2000 Alero 2.4L and am having the same problem, but worse. Whenever I brake to a stop while in Drive, the engine stalls sometimes. I thought it was the torque converter going bad. I tried the cheap fixes first when fuel system cleaner and air filter. I took it to a parts store and they pulled the code. "Service Engine Soon" light came on. "Too Rich Bank 1" was on the screen of their code machine. I was thinking fuel filter on my way to the parts store, but wouldn't a clogged fuel filter make it too lean? I have cleaned my air filter and have ran two tank fulls with "Sea Foam" additive. I have had some better low-idle performance, but it hasn't cured the problem. Today I held the throttle down at 1,500 RPM in Park to see if it was running steady, and the engine began to stall! I had to let off the throttle so that it wouldn't stall. That's when the "Service Engine Soon" light came on. About a year ago, I had the fuel injectors professionally cleaned at a shop. Is the throttle actually electro-mechanical? Is there a throttle relay or servo that's going bad?

2005 chrysler town and country when i start the van it shaking vibration hard in park and in reverse it and in neutral and in drive it perfect.it drives good on highways no shaking


try to increase the idle-rpm..
Example - at standstil condition when you start your van, have look at rpm... say 1000 or 1200 or 1500.. whatever it may be..
Keep idle-rpm a little bit higher, if previously it was 1200rpm then set it to 1500 rpm..
If the problem is solved then..
1) clean ur airfilter
2) check spark plug condition
good or bad... if bad then replace..
3) check fuel supply line, if it is damaged or folded

P0300: SOMETIMES rough idle, shake a lot OR less power above 50mph then got this code


Spark plugs in your car are good for 100,000 miles. try changing fuel filter and add a can of B&G 44K fuel additive. This stuff is the best on the market and only available at dealerships. It conditions fuel pump and injectors, also absorbs water in fuel (methanol). Try this first, your car is too new for any other problems. this should help drivability and fuel mileage. If Nissan does not have B&G, I know Toyota does. Also stay with 91 octane fuel. Check oil and coolant often. do not risk overheating in traffic, watch your gauges......

It has this problem at Idle? If this problem is while the vehicle is moving but not at Idle or when you rev the motor check your A frame, Connecting Rods, Tie Rods and Ball joints. You also want to check to loose lug nuts or a bent rim. If it occurs when it sits at idle check the motor mounts and bushings and the transmission mounts and bushings.

Car idles rough in park also runs rough in overdrive


Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

around 75,000 miles, plus or minus 15,000 or so. when you say shaking, do you mean a rough idle? thats not cause by your transmission per se...

Sounds more like a weak fuel pump, idle controller, or well, theres a bunch of reasons you could have a rough idle.
