#31 of 208 Engine hesitating and "bucking" at highway speeds
Jan 07, 2008 (4:19 pm)
Hi, I've been having some problems with my 2005 Chevy Cavalier 2.2L automatic. It's at about 95,000 km. I was driving it down the 401 highway and I could feel it hesitate slightly occassionally. Then I hit a patch of really bad stop-and-go traffic and as I was idling in drive, the car stalled out on me twice. I had no trouble restarting it and then if I idled in neutral it did not stall again. After that incident I drove it again without any similar problems for about 3 months.
Recently, however, I was driving to work along a two lane highway (about 100km/h...(55mph?)) and it started doing the hesitation thing again...this time it was very pronounced, even bucking occassionally. I got to work and when I went out to my car after work and started it (cold engine), the tachometer was going up and down like crazy and when I started to drive it was hesitating and bucking again. So I took it to a garage when I got home and they checked it out. They told me that when they test drove it, they couldn't find anything wrong but it "has a history code for random misfire and front O2 sensor. Spark plugs look good". They replaced the fuel filter which was very "gunky" (their word, not mine...) and added gas line antifreeze. Of course, driving home from the garage my car acted up for me...just slight hesitation and very intermittent.
Soooo, wondering if this could be a problem with the O2 sensor after all? I've read that they can malfunction in such a way that they do function intermittently and don't cause any engine codes. And by the way, no warning lights ever came on at any time during these problems...no check engine light or any such thing. Thanks for your input! Cheers!

ok, I have been having the exact same problem with my 2005 auto cavalier. Its still under warranty and I took it back to my dealer and they replaced the same sensor as yours. They also could not find anything wrong with the car on test drive. But conveniently two days later it stalled on me. This has been happening for a year. It goes through periods of stalling everyday to periods when it stalls once every three weeks. I am at my wits end. The sensor has been replaced already once and reset twice.
The first thing to go wrong was my timing chain... ya thats right, no lying... about 1 year after I had the car. Then the stalling began. This car has been nothing but a never ending hospital stay. Its like caring for a sick relative
I do believe the 2005 cavalier is officially a
Please let me know i you have any other ideas... this seems to be a common problem with this model

Friend of mine has a cav that does the same thing to him about 1 time each year . His has problems with the ignition coil system . The location they are in allow water and dirt to get onto them and corrode them until they get hot and begin to short out.
Let it sit a few minutes and would fire back up and run poorly for maybe 10 minutes and die again..
Does yours have a ignition coil pack assy ? If so the coils will be mounted on a metal plate which is actually a module plate for the coils to fire. I would check here first if you are losing spark. Have your mechanic check it or Try to find a used coil pack assy to test it with

I CHANGED THE IGNITION WIRES AND SPARK PLUGS BUT THE PROBLEM CONTINUED. i HAVE SINCE CHANGED THE IGNITION SWITCH AND HAD THE FUEL PUMP HARNESS WIRES CHANGED. ALTHOUGH THE CAR STILL IDLES A BIT ROUGH AND SLOW, IT HAS NOT STALLED OR CRANK-NO START SINCE THE AFOREMENTIONED REPAIRS WERE DONE ON THE CAR. I'M STILL KEEPING MY FINGERS CROSSED.
#35 of 208 Cylinder misfire
Feb 22, 2008 (9:00 am)
I have a '97 Cav with the 2.2 OHV. I have an engine code of #1 cylinder misfire I have replaced the plugs, wires, injectors, and fuel filter. The condition still exists and I am running out of options. The vehicles does run, but consumes a great deal of fuel because of it. At idle and while driving the misfire is present. Any help would be appreciated. Thanks
#36 of 208 Engine shuts off while in park or at a stop.
Feb 26, 2008 (8:30 pm)
I had this problem for over a year. Every once in a while when I stopped at a red light or just have my car in park my engine would shut off. I have done everything to it from changing spark plugs, coil pack, CAT, sensor, Cleaning injectors and replacing fuel filter. It got to the point where it would start turning off at every single stop light. I was finally able to find the problem. I had a bad fuel pressure regulator. Since then my car doesn't have the rough idle and it stays on.

Most likely a clugged up Catalic converter, I had the same problem with an old van with 350 engine.

Hi, I have a 2001 Cavalier with the 2.2L and 5 spd. Every so often when I go to start the car it won't want to start, and I'll have to hold the key for longer then normal as the car barely sputters to life. Today it did something similar, except that even holding the key for a while wouldn't start it, so I gave it some gas and it started, just like you might have to do with a carburated car. So, idk if it's the fuel injectors or what. And idk if it's even really a big problem if it only does it occasionally.
#39 of 208 2001Cavaliler- Car Bucks 99K in miles
Mar 31, 2008 (9:05 am)
i'm a car idiot, but I am an observant driver. my piece of junk cavalier recently starting bucking while driving. no specific speed, weather condition or road conditions. 1st noticed it about 3wks ago. bucked on highway driving at 60 MPH. RMP dial jerked w/ each buck. thought it may have been due to windy conditions- but there was no wind. did it a few more times. my husband filled the tank w/ premium fuel, put in dry gas and it appeared to run smoothly for a few days then the problem started again. I have taken in into the mechanic 2 times. the car does not buck when they test it and nothing turns up on the scanner. check engine light never came on. car continues to buck . before taking it back to the dealer i'd like to get some suggestions on things to try or recommend to the mechanic. Dealer repairs are too costly would like to avoid taking it to them. besides for every other issue I had it took the dealer ( the experts) 2-3 times to diagnose and or repair. I even left her one day w/ a broken sideview mirror! would appreciate any help given!

like you, i don't know much about cars. my situation was a little different than yours. i was dealing with a "crank-no-start." as it turned out, my problem was fuel pump wiring problem. perhaps, you can try changing the fuel pump (should be changed every 15K miles). or perhaps, try getting the fuel injectors cleaned. good luck, wish i could have been more help.
