I get a popping noise turning corners but seems to be happening more often

I replaced the crankshaft and camshaft sensor we have fuel going thru and spark fuel pump is good it turns over but just won't start it happened from one day to the next it was working fine.

Hey! I blew my last engine in my Bonneville (stupid teenager I know) and I recently dropped in a used one. It was running rough and had a CEL (check engine light). I cleaned the EGR valve with a steel brush and carburetor/throttle body cleaner as this is what I was told to do after the code was diagnosed. After I refitted the valve, the car ram much smoother for around 5 miles. But then it started running rough again. I have cleaned it twice now and this problem continues to occur. Any tips on how to fix this? Thanks!

when I try to unlock the doors with the fob it wont unlock and the power window and door lock buttons stopped working

It won't start only turns over also water pump started leaking earlier same day what do you think.

Need to bypass security system

Without symptoms will just quit running while driving. No indication to start for 5 to 10 minutes will start quickly and run perfect. Has no special time or event may run for 1/2 up to 2 days before stalling. Then after 5 to 10 min. will start and run great. Had some idle problems today tho. Does not show a code running or when stalled. Replaced fuel pump and ignition module to no avail. Full of gas no over heating.

We have had a continuous battle with water from the AC system draining to the interior passenger floor. What may be the best solution to clear this up?

Car runs good then start to jerk and stall but not cut off

Then noticed the message center stopped displaying any info.
Would the missing belt have caused this to happen?

the fluid seems to be alittle over full but havent added any fluid lately, there is 163,000 miles. any ideas whats wrong or any quick fixes? the motor is running fine and after the car shifts into the gears, it runs fine but any shifting, it jerks.

I HAVE REPLACED UP-STREAM OXYGEN SENSOR ALREADY AND NOW WHEN I HAD IT JUSTED IT SAID DOWN-STREAM , EVAC SENSOR I HAVE NO IDEAD WHAT TO DO!!

does it require professional help changing the battery wires?

Also is worse as outside air temperature is warmer. It becomes more apparent. Also will intermittently surge as accelerating is taking place, but not always.

the other day I left on a trip I checked everything and it was ok. along the way during my trip. when I slowed down to take a turn onto a junction towards my destination the car all of a sudden started to rev up and there was no acceleration in speed but the gas started to go down really fast.. I made it to the town with only 1/4 of a tank left in the car. and I made this trip many times before. so it shouldn't have used 3/4 of a tank in that little mount of time/ miles. but now every time I start the engine. it runs rough and you can smell gas... any questions what this is?

I am experiencing a squeaking from the engine and it only does it when it gets warm outside. It sounds like a small dog barking/squeaking..In addition only does it when im sitting still..when it motion it doesn't do it..or I cant tell cause the car is moving..one or the other...I was originally told water pump. Replaced and it still does it. Soemthing is heating up and no one really, really know without taking the car apart

I am having minor electrical issues with my 2004 Pontiac. The gauges act up but eventually go back to normal. Sometimes when I open the doors the radio doesn't turn off or the interior light doesn't come on. Sometimes the headlights don't operate on daytime mode but work fine on manual mode. I have checked the battery cable for corrosion. I also read online that sometimes the battery cable could be faulty. I need to know if this can lead to further issues or if anyone knows of a solution. I know electrical issues can be complicated and costly.

Is my temastate stuck?

car was bouncing and pulling and jerking side ways when hitting bumps or pot holes. With new shocks the car rides worse now with new ones. Was told they needed replaced because they were wore out and leaking oil. bought shocks at auto zone and had them replaced was wondering what to do

How can I solve this problem with the oil gauge?

Where can I purchase a piece of metal above rocker panel in front of rear tire. Is there after market kits I can buy?

heat is lost after replacing the battery. Would like to reset by removing the fuse and replacing it to reset.

Dinging when in drive

Can someone send me a picture of a correctly indexed temp actuator? It would b appreciated

The cable is not broke and I can here moter moter run. Cable is attached at each end but I don't c it hooked anywhere in middle.
