Last month my car started revving up randomly while in park. Once I put the car in drive it would pull forward on it's own speeding up to 40 mph in the worst case. It ran so rough pulling and stopping the only thing I could do was put it in park until the RPMs came back down to a normal rate. From that point on, every time I started the car when it wasn't warmed up this would happen. It used to only take about a minute for the RPMs to settle and the car to run fine. Now it takes about 5 minutes of warming up, settling and then drives very poorly in first and second gear.

One month later the car hesitates when given gas, begins to "rumble" slowing down, and feels like it will stall out as the cars RPMs approach 0. I took the car to a mechanic and they found no problem. They said the RPMs were lower than normal on idle. I read online that there could be a vacuum hose leak causing air to be forced into the engine causing the issue but that doesn't make sense.

Today while turning in an intersection my steering wheel locked, pressing on the gas no longer moved the car but my radio, air conditioning and engine... were still running. Luckily I didn't hit anyone (or was hit by anyone). After restarting the car I regained control over the steering and gas. Driving home after that the car wouldn't accelerate properly and hesitated constantly. It was as though I was driving a manual transmission car and shifting gears poorly...

HELPPPPPPPPP :(

In terms as best as I can describe, my car sort of kicks when I'm driving. Switching gears does not make a difference. When I drive speeds as low as 35- MPH or going up a hill, my car seems to 'kick' or 'stall' in a sort that the car jolts back and forth a little. It pisses me off and gets old that no mechanic can pinpoint an issue or fix. I am SO tired of wasting my money on bullshit answers that I'm not getting answered to my questions. When I drive up to 50MPH for a certain amount of time. the same concept applies. The car just kind of kicks as if it is dying. Battery, alternator, starter all been replaced. FML and yours!

The problem started with the security system messing up. When you tried to start it, it turned over but wouldn't start. Then you had to wait 10 minutes and it would start. Then it started to stall while driving. First time it stalled was about 40 miles away from home. No garage seemed to be able to find a problem with it. We finally bypassed the security system. So far that seems to be fixed. But the car is still stalling. Now it stalls about 10 minutes after running, or when it gets warmed up good it seems. If you wait 15-20 minutes, so far it seems to start. Of course when it stalls, you lose power steering, brakes etc. The first time it happened I was on a busy interstate. Luckily I could pull over on the shoulder without causing a major accident. Someone mentioned it might be the coil. When it gets hot it shuts off and then after it cools off, it runs again. I don't want to start replacing alot of parts unless they're the problem. I can't afford another car right now. Any help would be greatly appreciated before the car kills me or somebody else.

This car had this problem when I bought it but I had NO OTHER choice, I had to buy something. Besides, they told me that they "thought" that they may have fixed it....WRONG! When they had the problem with the car, appearently everything was checked & replaced but with no luck. The 02 sensor was replaced a couple times, tune ups, fuel filters, etc....They even hooked it up to a diagnostic machine and it didn't detect a thing.

I am NO expert but............1st of all; the car only stalls when i take my foot off the pedal. I could be doing 65 down the highway, but as soon as I take my foot off the gas....DEAD! The car totally cuts off. No funny sounds, hesitation, smells, etc. It just dies. When I 1st start the car (the initial start up), I make it about a couple blocks before I have to drive "two footed" so the car wont stall.

I noticed that the old owners put a new stereo system in the car. There were a few more problems with the car when I first bought it that have since stopped or just got worse. All electrical issues. For example: The car has day time running lights. At times I would have to actually turn the lights to the "off" position b/c the high beams would start going nuts and flash like a police car. But that has stopped, so idk wth that was. My blinkers stop working whenever they feel like it, and then will work again just like that. I have a "service engine soon" light AND a "Check engine" light; both light up on occasion. So does my traction control, etc...... But nothing is wrong?!?!?! I beg to differ. However...........if there is already a really screwed up electrical problem, would the diagnostic machine actually be able to find a problem???? I personally think that either the electrical system was screwed up when they put a new radio in the car OR thats a whole other problem on top of the stalling.

I've been told to have the "throttle plate control motor" checked out. Something that a diagnostic test may not detect and something that is NEVER thought to replace. Has anyone heard of this???? Please help, I can't take it any more. And I have a 6 year old that I have to drive around in this death trap!

OK this was my moms car so needless to say she babied it. i got the car september 11th 2010 and i replaced plugs oil all lights o2 sensor and just cleaned it from top to bottom! now i have had a GM mechanic (family friend) look at it and he said it sound like the coil packs,coil carrier, or a bad cylinder ? i honestly still have no clue im hoping someone can say they are having the same prob and tell me wat it is ? it will start and run real rough for bout 4 seconds or so and the smooth out till it gets warmed up... then while im driving down the road it feels like it is cutting in and out but only wen im going up hills??!! and stopped at red lights it idles real rough ! plz some one help me i cant aford to keep guessing cjspeedin865@aim.com or better yet call 478-986-0821 thx alot .... cody

I am driving down the freeway and the car died. I coast to the next exit and try to start it again. It cranks but does not turn over. My radio still works, lights still work but no engine? Checked the water, oil, lights, all is well. No water in the oil, no oil in the water. I un-hook the battery to see if that will reset the computer. Waited about half hour still the same thing. I had it towed home. I don't know what to do. I can't afford a shop. I had this old guy look at it. He checked to see if it was getting juice. He took the battery to auto parts store and they said it was old and might not have enough amps to start the vehicle. But that doesn't explain why it died while driving. The alternator is good and so is the starter... Help holocker10@msn.com

my Pontiac stalled while driving the other day luckily i was able to pull over safely. when i attempted to turn the car on, it turned on with no problem. but the car stalls while it is idling at a stop light. could it be the crankshaft position sensor, idle position sensor, mass airflow sensor, or does it need a new fuel line ornew fuel pump? i read similar complaints from owners of Chevy Pontiac's who found it was the crankshaft position sensor but one individual had to replace all those things before finding that the mass airflow sensor fixed the problem. did it need all those replacements? help!!!

Well my car stalled out again... so i took it to the dealer. I told them what was wrong with it and left it to them for the day. I told them to call me when they find out what's wrong with it. When i got the phone call they informed me that my fuel pump was leaking, the ignition coils burnt out, and the whole cooling system had to be replaced... in the end my $7,000 car ended up costing me $9,000 and thats if everything is smooth sailing from here on out... and with a pontiac I highly doubt it..

Well, occasionally there is a problem starting the car, but normally after a second attempt to starting it the car will fire up and i'd be on my way. Well today i had the same problem so i turned the key a second time and it stopped... well half way down the road it cut out on me. My RPM's got stuck at 1000, i lost power steering, and my gas pedal was damned to not working... so here i was rolling down the street and onto the shoulder of the road. Anyway, i took it to an autocenter and they told me they don't know wuts wrong with it... why? b/c it worked fined when it was brought to them, but they recommended me to go to a Firestone (who goes to firestone?!), so i have yet to solve this problem... no one knows wuts wrong... stupid pontiac!... why can't dealers be more resposible in honoring a warranty?... i'll be back
