Question about Cars & Trucks

1 Answer

GMC R1500 5.7L. It has been in and out of a mechanics shop for several months, thankfully i only had to pay once. But it still has a problem, and the problem manly happens when the vehicle is idling. When the vehicle idles for to long to starts to surge and then eventually die. The longer I drive it for the quicker it will die when idling, or even slowing down. Every time i took it to the mechanic i said the distributor was bad, and it was. for a day it will run great and then by the end of the day it will be back to its old dieing self. I just got two new code, 32 and 42. Any tips on what I should do, and how do I fix those codes?

    I have already checked the fuel pressure and it is right where it needs to be.

If the codes you are talking about are P0032 and P0042 they are both related to high heat in O2 sensors I would start by checking the wires for damage, that is the #1 cause. However with minimum information on your vehicle, that would be my best guess. keep in mind i do not know the year, miles and am missing a lot of pertinent information.

SOURCE: 95 GMC Jimmy 4.3l W vin rough idle

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

Reduced engine power kicks in several times per day even when on the highway

not sure what make and model you have , but if it kicks in once in a while from the limited info, I would say your coil is getting bad. let me know what kind of vehicle, that would always help thanks

Power door locks

If all of them quit working at once, it's either a fluke or your main switch in the driver's door trim has gone bad. Otherwise the actuators for each of the door locks have all simultaneously gone bad.
Can you clarify if all went out at once, or if just one went bad or was it a gradual occurrence? A body shop or mechanic shop could fix you up (body shops may be able to give you their body rates as opposed to a mechanic shop rate).

After getting my 95 GMC Sierra 1500 5.7L V-8 back from a failed emissions test I let their mechanic fix it( or pass smog) However, now when the truck is in park the rpm's are at 1200 about 300...

I had an 89 Chevy Silverado with a high idle problem, A lot of money later and a lawsuit against a repair shop that said they fixed it and they didn't caused early engine failure and they wind up paying for a new engine. Long story short, I found out the main cause was I had to replace the throttle body gasket because it was bad causing more air intake and the on board computer tried to compensate for the air by adding more fuel therefore, high idle. I hope this helped.

Own a 2000 GMC Jimmy. Had the thermostat changed out as it began over heating...severely. Went almost 2 months after new thermostat put on without any problems. In the last week began slightly overheating...

Save yourself money. take to mechanic and say that is overheating. Do not suggest repair. You will have the preforming unnecessary work. In my home remodel business, whenever customers wanted to tell how to do it and micro manage it cost them extra for doing work that did not have to be done or not related to project.

When it come to airbags take back and let the fix it.It could blow up in you face and they cost $2500.00 to replace so i think if they blow it they can pay for it.

My engine light in my 2002 GMC Sonoma has been on for the past four weeks. Yesterday I had an oil change done on my truck with a local mechanic. He turned the engine light off, but it came on soon after...

Your mechanic should know, he reset the light. Battery life can be as short as 24 months. You need to look at the age of the battery, if you bought a low price battery, it is a 24 month one. Check the cables on the battery and make sure they are clean and tight. You can get the OBD codes from any autoparts store, they read them free.

I have a 03 Cadillac CTS and have had to replace the thermostat 4 times now at over $500 each time. I just replaced it a couple weeks ago and the engine light is on again so I took it back where I had it...

Replacing a thermostat once is all that is required

You put the old and new one on the stove in a pot
of water with a therometer, and watch when they open

Why would you pay $500 for that job,not once 4 times
$2000!!!!! You should be doing that type of work in your
driveway. You see the end results,learn from it

The Check Light indicates a possible system failure
The codes you get tell you what system,then it gets
complicated. You need OBD2 knowledege and possibly
trouble charts to work from
Your repair shop should solve this, no problem

Lets go with common sense
---4 new thermostats don't fail,not even one
---Your mechanic has no connection to another
private repair shop,that being a dealer,so neither
he nor the dealer is going to do anything for free

Common sense again,your warantee was 3 years,maybe 4

Recalls would never happen, even on the presidents limo,
even after the govt bail out

I would check with the dealer,in person,not the service
advisor out front.
Get into the service bay and talk to a tech about the issues
then have the service MGR pull up Tech Service Bulletins

Your shop has had these issues,have they ever solved one,
they most likely network with other shops to get answers
and should have a tech line they pay every month ,they can call.

I had a trans repair shop and I had a couple of them.

Sorry I can not give you first hand solutions,but your in the
middle of a dog & pony show,not a realistic diagnostic approach

If they can't fined anything wrong with the car itself the problem might be in the sensors. IDK what kind they use in that car, but the mechanic might not have the electronic equipment to diagnose, check, or solve the problem. They may have been damaged when they fixed it, might be wear and tear, or they probably just have to be reset/ re-adjusted. Most people don't bother to fix them if that's the case cause they see it as a pointless expense if nothing is wrong with the car it's self. Another issue is replacing them. Most mechanics will opt to replace them cause it's easier and they can charge you more...then again it might be expensive for them to ship it somewhere so some one can actually fix it, and then pay them also. Most mechanics don't know much when it comes to circuitry. In ether case most people don't do anything about it and continue to use there car with all the red flags on. Ether way if it's going to brake down it will anyway and you'll still have to pay to fix it. Usually at that point people usually decide it's time for a newer car anyway and sell, donate, or junk it. If you really want to keep your car though I suggest you or some one you know to just look it over once a month and see if you can see anymore wear and terr. It's a bit obvious sometimes if there's anything physically with it. Also have a mechanic give it a thorough inspection once a year. Good Luck
