The engine light turned on like 3 years ago. I took it to have it checked at the shop and my mechanic told me not to worry about it. I have had no driving problems with my car to make me think there's something wrong. I diligently service my car at the regular intervals. Yesterday my car failed the emission test and I need to correct this problem to renew my car registration. Do you know what exactly code P2440 means and how much would it cost to fix it?


How much does it cost to replace a belt tensioner assembly

Heard a grinding sound, shut the engine down. There was evidence that A/C charge was dumped from the blow off valve on bottom of compressor. Did the expansion Valve cause this? Is it hard to change? Shouldn't there be a high pressure switch to shut down the compressor? Can the expansion valve be changed easley under the hood only? Should I look for other reasons it happened? 130,000 miles.

if i can't clear the heater core, what is the best way to remove the heater core on this 1992 grand prix

how would you recommend i flush the system? the radiator is good. could i take the side of the hester hose that i can disconnect and take my garden hose and connectit to the heater hose and flush it that way?

would the blend door before the heater core cause the same problem as a plugged heater core if the door was not working right?

Where is the PCV Valve located?

I have a problem with warm to no heat. the upper and lower radiator hoses are hot one side of the heater hose is hot the other side warm could the heater core be plugged? if so could i try to flush out the system? or replace the heater core Need help

The car was running fine. No engine lights, no major problems. About a month ago the car was overheating, i took it to a shop and was told i needed a new water pump from a visual inspection. i saw the antifreeze was low. i replenished the antifreeze and had to replace it again immediately, so i did. the reservoir then stayed full. I drove the car without any problems until the holiday weekend. i drove 300 miles to my parents with no problems. on the way home from the visit the car engien started knocking. I pulled over, the car was not over heating, the temp. guage hand was a little high, but not over the half way point. I checked the oil and the coolant. They both were ok. i waited 40 minutes before i started back on the highway, within 10 minutes of getting on the highway my steering locked up, and the car shut down. i got to the side of the road, and the car would not restart. it would sound as if it wanted to, but didn't. looking under the hood, i couldn't see any obvious problems, broken belts, low fluids, or oil leakage. Could this been caused by a bad water pump?

I was rolling up the drivers side window and it was a little slow. I rolled it diown and now it won't budge. I was wondering if it's a bad motor or switch. I have a multimeter to help testing. I have the door panel off and wires disconnected

I have a sever rattle under the front end of my car while driving slow. Any little change in the road top surface, be it small or large allows the rattle. It started out a few years ago as a slight/fait rattle, but has gotten extremely pronounced over times and can drive you nuts while driving slower. I have had the dealership (not a pontiac dealer, but reputable GM dealer I always use at a Chevy dealership) check under there numrous times and they say everything is tight, and have tightened a few things a little more to make sure. They checked the struts too, and they are fine. I know I have had a wheel bearing that they have been watching the last two years, and finally, it is starting to get some play in it, which they observed upon my recent visit for new brakes. Can a wheel bearing possibly cause such a clatter? My husband's Mazda pickup had a wheel bearing go bad and sounded like the engine was running really loud and hard (so thought we had engine problem, but ended up being a bearing--strange). So, again, can a bearing cause such a rattle, especially after it gets worse over time?

My low coolant light is on, but my radiator is full and so is my overflow tank? Any suggestions?

How do I change the oil pan on a 2002 pontiac grand prix? looks like it is pretty rusted and the oil pan gasket is leaking.

1995 Pontiac GP(SE) with 3100 engine. Brake pedel frequently (but not aways) "sticks" at the top of its travel position. By applying firm pressure the "sticking" releases the pedel and brakes can be applied normally. Doesn't seem to happen with car not moving (engine running).Does the car have a "proportioning valve" or does the ABS system take care of that aspect of the braking? Again, does not happn all the time but frequently enough to be disconcerting.

I noticed that my traction control sysytem is defective since 11-19-10till now. the message on screen started to pop up since that time. it started to show up along with the problem. i quit driving my car because of the snow,whenever i drive it,it gets slipped and drifted left and right as if it is dancing. i was about to make car accident for 3 times because of it. it is snowing heavily lately in MT so i can't drive this car while it has this problem.please will you answer my question with details about this defect and how much does it cost me to repair it.


My cruse control quit working and then 3 days later my headlights stop working tail lights are working and blinkers are working when I pull the blinkers to put the dims on they work but as soon as I let go they is nothing

Noise only when moving....sounds like something spinning...reminds me of speedometer cable possibly..driver side under hood

How do I know when the low beam headlights need to be replace? Does the Driver Info Display let me know?

The Service ABS and Service Traction system Lights come on and go off intermittently and while the light is off the braking is erradic and the pedal reacts funny, when light is on brakes operate fine.

theres a tsb that says the exhaust valve stem seals may be in need of replacement. ive no visible leaks... no smoking from car.. but it eats oil like a pig. (only 48,000 miles on it of mostly stop and go city driving). any clue how long a repair this would be and about how much it should cost?

how do I go about removing the cover below the radio to repace bulbs that light up the drivers and passengers side heating controls.

Sometimes low beam headlights don't turn on at night; when I attempt to turn the control to manual off/on for them, the switch on the lever won't turn them on, and goes back to off, what is wrong?

My 2006 Grand Prix just hit 75,120 miles (120 after the warantee expired) and the waster pump started "chirping" the other day. Today I noticed it is running hot and there appears to be some anti-freeze around the pump. Is this fairly easy to replace? I'm pretty handy, but not sure if I should tackle this. Also, should the timing belt be replaced now that I've hit 75,000 miles?

while trying to replace a brakeline, i accidently stripped out the connection to the abs module. not the screw-part but the thing the screw-part goes in. it has been temporarily jb- welded but i was wondering how to go about fixing it without buying a whole new abs module as they are hard to find and are expensive.
