Suburban :: EGR Code After Driving At Sustained Speeds Above Forty Mph
Aug 18, 2012
94 GMC 5.7 K1500 .... I have been getting an EGR code after driving at sustained speeds above forty mph. The code gets stored for say less than thirty starts then disappears until I hit the highway again. I took the EGR valve off, cleaned it with carb cleaner (really soaked it) until all the black crud stopped coming out, replaced the gasket and reinstalled it. Back on the highway and the CEL is on again (goes out after a few minutes/miles) and the code is back. I went to the auto parts store and got them to show me a replacement valve. When I shook it there was a slight rattle (which I assume is the diaphragm). On the other hand mine offered no rattle sound after cleaning so I'm wondering if the valve is pooched. Anyway my question: whether the problem is
a) the valve,
b) the solenoid or
c) dirty EGR passage in the manifold?
Depending upon the cost of the diagnostic (ie if it exceeds the valve) I'm probably going to just go ahead and replace it. I don't need a smog test until next Spring.

So I had a couple of hoses replaced on my a/c system and the refirgerant replenished. On a hot day (like we've had for the past several weeks) When just tooling around town I have it set to "max cool" (recirculate) and fan on "High" it blows air cold enough to freeze water! But when I hit the highway and run at sustained highway speeds for over an hour, the fan output (force of air coming from the vents) distinctly lessens.
This is regardless of whether I have it set to max cool or just high regular. The fan simply does not blow as hard. Now I have replaced fans in both my older trucks (an 82 and an 88) so as long as a '97 isn't too much different, I know the job isn't particularly hard or expensive. I just want to hear some theories as to why this is behaving as it does.

I have noticed a louder noise and increase in vibration during driving at speeds of 70mpg + ... What is the cause??

Ok so this is something I can't quite wrap my head around. I have a 1999 K1500 Suburban, 5.7L. I have only owned it a few months. The thing is, shortly after I got the truck, we took it out of town, where it died after a little over an hour of driving at highway speeds. I had punched the odometer to watch the gas mileage, and we had run it about 70 miles when it died. We got it to our friend's house, where we were headed anyway, and stayed over, planning to look at it in the morning because it was later than part stores stay open in our rural area. Thing is, in the morning it fired right up. So we headed home, and once again, after about another 70 miles, it shut down and refused to crank.
This time it happened as we were coming back into town, and on a hunch I said that something must be overheating for the problem not to be present until after an hour of road time. So we pushed it a safe distance off the road, and went and grabbed something to eat. After about an hour we made it back to the truck and success! It cranked back up and we made it the rest of the way home. Since I have driven it to town and back, and to my parents a few times, but never more than thirty or forty miles away. It never hesitates to crank, and sounds ok running. Although I will say, I have not owned a truck before or a V8, but it seems to not have the power it should (my thunderbird with a 3.8L had more punch), and I did noticed both times this happened that that problem seemed more pronounced right before it died. But I don't know if I just feel that way just because I am used to driving cars, and the truck is heavier. When it dies, you hear the starter relay click, and that's it.

I own a 99 Suburban 1500 5.7. The front blower motor stopped working on all speeds so I replaced the resistor, it still did not work. I then replaced the speed selector switch and it started working fine. Three days later I smelled a slight electrical burning smell and the fan stopped working again. I plan on replacing the switch again to see if that is what went bad. Whats causing this to happen? Maybe the motor is going bad and causing the switch to short?

I have a 2000 Suburban with about 170,000 miles on it. I'm getting an audible clicking sound at slow speeds which increases as the vehicle speeds up and also a fairly severe vibration which becomes noticeable at about 20 mph and becomes worse as the speed increases. I thought maybe driveshaft but things seem fairly tight. Also, this has gotten gradually worse over time.
Ok I figured out where the vibration was coming from...U joints in the front driveshaft are shot. Now I have another problem...I've removed the fwd u joint straps and according to the book, the driveshaft should simply slide to the rear into the transfer case so I can lower the fwd u joint but the problem is that the part of the shaft (which slides into and out of the transfer case) seems to be frozen/stuck. Do I simply beat on it with a hammer to break it loose or am I doing something wrong?

I've got a 2000 Suburban 1500 4WD with the Auto 4WD. I'm running into a vibration at highway speeds along with a clicking sound at idle speed which speeds up and slows down with speed. I've discovered the u-joint on the front drive shaft where it connects with the transfer case is worn and has play in it. Could this cause the vibration?
Also, The front drive train spins any time the vehicle is motion, which is to say the front drive shaft spins as the truck goes down the road, correct?

Trucks been running perfect for 11,000 miles atleast. its last issue was a bad turbo but that was my fault. No issues whatsoever since. 10 miles down the road from work last night truck had a slight miss in between 55-60 for four or five seconds, I put the pedal down and brought it up to 75 or so just to see if it was my imagination and it felt fine so i wrote it off. It ran fine to the house we're working on i wanted to check on before I got home.
Parked it, it idled down to 650 before it came back up to 750 and it never does that and sounded different then it usually does. so i felt something was definitely up. i shut it off, was at the house about a half hour before i decided to head home, started and ran fine, three miles down the road the slight miss came back, it seemed to go away if i got on it pretty good and when i let off but just cruising with slight throttle it had the slight miss.
Got to my road where i had to slow down and turn and it idled down and died. I coasted over, unplugged the icp sensor and it cranked for 10 seconds or so and lazily came back to life. I got it home running decent and parked it. Scanned it with my old super chips tuner and it came up with a p0340 camshaft position code.
Matched my symptoms i felt so this morning i decided id go back to work and grab my spare out of my wrecked truck. truck started and idled perfect. made it to the end of my driveway before the miss came back and then it just died. took the car to work, grabbed my spare camshaft sensor and my maximus scanner, came home scanned it, no returning p0340 cam code but i swapped the camshaft sensor anyway and watched icp and ipr data, the ipr voltage is where it should be and rises while cranking while cranking.
ICP is climbing to almost 3,200 psi and it will begin to run when it peaks out. she'll fire for 45 seconds after 25 seconds of cranking or so and then it'll just die. if it sits for a few minutes it takes a few seconds of cranking before ICP will come off of 0. I've come to the conclusion that it is making high pressure oil it is just dumping it as fast as it can make it. I changed the ipr out because that can do it, it didn't change anything so I'm on to believing an injector is dumping it as fast as possible.
Is it possible for something to come undone inside the injector to make it dump high pressure oil or will a bad o ring cause this? i'm leaning towards a failing injector as when it does fire and run its definitely misfiring and i just put new o rings on them when i swapped them over from my wrecked truck but that was like 45,000 miles ago as well..

2004 Chevy Suburban 4wd
My airbag light is on and my code reader, Innova 3160d, is telling me that the B0083 code is the Second Row Left Seatbelt Load Limiter Deployment Control (Subfault).
I Googled the code and came up with 1) passenger seat position sensor, and 2) front impact sensor 1 (driver's side).
Which one is correct?

Have 2001 suburban with the 5.3. Mechanic has replaced EGR valve 3Xs. Error code specifies "replace EGR valve". Each time car runs fine for 4-6 weeks (500-1000 miles) and then service engine light comes on. Shortly thereafter the car will not idle correctly (under 1,000 rpm) and will die at stop. I think the EGR valves are getting clogged up with carbon. Car has 130,000 miles on it.

I have a 2000 Suburban 4wd that has a p0300 code. The misfires are coming mainly from #2 and #7 cylinders. Misfires only occur at idle. over 1500 rpm the misfires disappear. I have put new A/C Iridium plugs in, new wires, and new coil packs on both cylinders but the problem is not any better. All 8 fuel injectors all go to 55 psi when activated and drop to 28 when released. All tests were done with my Snap-On Solus.

After driving through high water (only 12"-18" deep), my 2002 Suburban stalled. It restarted but runs rough, doesn't idle well, and still stalls and sputters under acceleration. A week later (it's been dry and I've driven it 70 or so miles since the water), it's still stalling and sputtering. Under braking, I must keep the accelerator down enough to keep the RPMs slightly above 1000 or it will stall. Obviously something got wet that shouldn't have gotten wet.

OK so - I had the rear axle bearings replaced, but I'm still hearing a rotational scraping noise while moving (whether gas is applied or not, or whether braking is applied). Gets slightly louder the faster I go. But when I turn, the noise goes away. It's hard to pinpoint where the noise is coming from. My wife swears it's in the front; to me it sounds like it's in the middle (so it would be being transmitted from the source).
I took it back to our mechanic, but he can't hear it very well - he admits that his hearing is not what it used to be (he's in his 70s). Only thing he hears is "gear noise in the rear"... meaning he'd have to replace the differential in the back which would be prohibitively expensive and not worth it. He said I should come back in a couple weeks when his younger employee will be back so he can listen for it.

I have a 1999 GMC Suburban(5.7) with 173k miles. When the outside temperature is above 80 degrees F and I have been driving for about 30 minutes, I get a hard/firm shift from 1st to 2nd. It shifts to the other gears normally. When the temp is below 80 degrees, I can drive all day without any problems. Any clues for what may cause the hard shifting on hot days?

I am working on a99 2500 4x4. 7.4 Replaced 230,000 engine with 90,000 engine.I had to fix a bad oil leak from the oil pressure sensor. Replaced it and delivered it.
Ran great Gal was driving at 50mph. Engine died and wouldn't start. She fried starter trying. Replaced starter, has no codes. 59-60 lbs fuel pressure with key on then holds 50 lbs. 60 lbs while cranking. Has spark at plug. NO security light staying lit or flashing. flashes then goes out. Smell of unburnt fuel is strong. Also no oil pressure at gauge when cranking and her key fob doesn't work.

So the other day I was driving to my storage locker about 30 miles away. All of a sudden my rpms would shoot up to 2000 rpms then back down to 1500 . Slowly they would go up higher every time. On my way back I was about 2 miles away and I lost 3rd and 4th a presume. I would be going 20-25 and it felt like it would be shifting up to third but would shift down to 2nd running 3500 rpms. I had to go 20 the rest of the time. Finally I got home and realized my dipstick tube wasn't in the tranny and must have lost oil. So I got it back in and added more. Thought it was the filter and oil so dropped the pan and replaced it. Still nothing.

I can drive below 40 mph and nothing, once I hit the freeway engine light turns on and gears start slipping. I erase the code and it runs fine at first this would happen once in a while but lately its every time I get on the freeway. I cant keep driving and erasing the code, Every shop says I need to replace the transmission?
