Chevrolet - Suburban :: 1999 - Muffler Size Damages Engines?
Jul 9, 2015
I have a 99 chevy k2500 suburban with a 7.4 liter engine. I had a tune-up two weeks ago, all was good. the next day I got a muffler put on, the guy said I didn't need dual mufflers, it was a waste of mufflers, and that I only needed a single muffler and single pipe. Well, after that I felt the truck was limited on power and acceleration. I could not pass or accelerate up hills. I took it up hwy 80 to Truckee and on the big hills it had no acceleration at all, When I got to Truckee I pulled off and listened and heard some unsettling noises from the engine. Took it to a shop, (weekend, no one open!) a 76 station was open everyday, they looked at it the next morning and said the engine is blown and I need a new engine. I was upset. I towed it to another place that I knew and trusted, they said the same thing. but they also said, "this muffler system is too small for this engine, this could have caused the damage." And other shops have agreed. Do I have a case?

What size is the pitman arm nut to steering box in a 1998 suburban? Some one said 34 MM. Don't want to buy the wrong size of socket.

I have a 1999 Chevy Suburban K1500 4 wheel drive. It has a 5.7 liter engine and has 360,000 miles. I recently had a fuel pump put in last year. It is now running sluggish when I accelerate it will not go. This happens after it seems to warm up about 15 minutes of driving. I just replaced the fuel filter thinking that it may have been plugged up but it is still running poorly. When I put the fuel pressure gauge on it, it read 61-62 during start up and then dropped down to 57-59 (pulsates rapidly) after I started it.

OK... I know next to nothing about cars. I have a '99 Chevy Lumina I just bought in February. It has been one problem after another. The water pump has been changed and I just got my car back on Monday because there was a leak on the timing chain cover. Now, the car is smoking on the passenger side. Its not a light smoke, but its not heavy yet. I noticed it on the way to work this morning. I opened the hood, it is coming from the left side (looking at it, so the passenger side) of the engine maybe kinda underneath it. I dunno what to do, but I'm ready to push that thing into a lake.

Well I just set the timing on my rebuilt chevy 5.7 1999 suburban. It still runs sluggish when I accelerate and idles nice when it'd parked. I rebuilt the whole part part of engine. This is what I did notice when I cleaned under the lower intake manifold where the fuel injectors plug in. Here is a attached picture.

I have just swapped a new Vortec V-8 engine into my 1999 Chevrolet Suburban K1500 4*4, now when I start the truck and put it into reverse (foot still on brake pedal), I let off of the brake and the next time I step on the brake pedal the truck stalls. What would be causing this? I have no error codes on the computer, my fuel pressure is good, I just replaced the fuel pump. I think that it might be a sensor somewhere, but I am not sure where to look.

My Sub makes a wonderful ticking noise that resembles a turn signal--it continues to tick until i apply the brakes. i have just replaced the brake switch and the noise is still there. All the lights on the vehicle are not illuminated while it is making the noise, it makes the noise while either driving or idling.

So I used my 2000 silverado 1500 to remove a willow trunk from my yard. 4 Lo, took a bit of work but I tried not to overdo it. Now, truck sputters when accelerating. Once it gets going it's good but the startup is sputtery and bucks a little. What did I do?

When the outside air temp reaches above 70 degrees, my Blazer will die going down the road. It will not start for about five minutes, then starts up again. Also, I have took the overflow cap off, poured water in it, and it would start up fine. I don't know what is causing the problem, it runs great in fall/winter, but when it warms up, it starts doing this?

My 2008 Malibu service manual states that the check engine light should briefly come on when I start my engine. When the engine is cold this does not happen. Also, it happens infrequently when the engine is warm. My Chevrolet dealer says this is normal as the light checks out when tested. Chevrolet has not given me a difinitive answer on this. My concern is that if this is a problem it may surface at another time when the light should go on and cause damage if not attended to. If the manual says the check engine light should go on when the engine is started and it doesn't, doesn't this mean something is wrong?

When I put my 2002 TrailBlazer into 4WD, it seems normal as long as I have my foot on the gas, but when I am "coasting" or just slowing down, the car feels like something is dragging on the engine is dragging--sort of like when one tries to drive with the parking brake engaged, or like when you shift to a lower gear in a car with a manual transmission and it slows the engine down. I don't recall this being a "feature" I've had before.

2000 Chevy Monte Carlo 3.4l - The problem that I currently have is that the car will not idle smoothly, it bounces between 600 and 800 rpm. I have replaced the spark plugs, wires, fuel filter and thought I checked the hoses. Just got done changing the upper and lover manifold seals, during which I replaced or cleaned what ever was suggested by the place I purchased my parts through. I am at a loss, I have begun to notice that there are small fluctuations on the highway when I am using the cruise control and am on flat land.

02 Chevy Impala with 177,000 miles has re-starting problems for last 20,000 miles. New Battery, cleaned throttle plate, new fuel pump, check engine light on (emission problem was told to me by mechanic). Whats going on?
When the car runs it runs very well...to get the car started, just wait, sometimes 5 minutes, sometimes longer than an hour. All the time periodically cranking the engine...just does not start. But when it does start, it runs very well.
This problems occurs only after the car has started and is warm. Let it sit for a while then restarting the problem occurs.

My 2003 Suburban shakes when I drive over 70 mph. I don't know if the tires need realignment?

I have a 1990 suburban that has had a rebuilt x-mission about 50,000 miles ago. At this time when I drive there is a hesitation, split second, when running on flat road. It happens when going up a hill, too.My mechanic said change the: plug wires, then the plugs and rotor. No difference.
I think the thing is dropping out of OD for a split second and then going back in. If I drive in 3rd, I don't think it is happening. Isn't there a relay or solenoid that controls this function?

I have an '05 Suburban with starting issues. When it's cold out (below 40 degrees) and you turn the key, all accessories come on but truck will not crank. It then seems like the power just cuts off.......dash lights go out but gauges are fixed in place and a couple of seconds later, I hear a strange buzzing noise from the dash area behind the radio and the gauges will then go to power off position. Then if I try to start it, there is nothing, no lights on dash, no starter engaging, no clicking of the relays, nothing. I tried, on a hunch to disconnect the ground lead from the battery. Had it off for 10 minutes or so, put the cable back on, tightened it down (wasn't loose to begin with) and it started right up first try in 20 degree weather. I had previously had the battery and alt checked and both were good.

2007 Chevy Suburban, 65K milesLet me start by saying I took this into to the dealer and they found nothing!
When I accelerate, I get a "flutter" in the engine. The best description of this flutter is that the RPMs go down about 200 or 300. I think it feels like it is sluggish when it accelerates. It is most obvious during the 35 - 60 MPH range, but you also see it when cruising at 70 MPH.
I tried adding some fuel treatment and ran some 93 octane through it to see if it was the fuel injectors, with no change in the behavior. No error messages or engine light is on. Regular oil changes and services (60K service, every 3K miles for oil change). Driving behavior has changed since I bought a Prius 3 months ago. It used to be driven 40 miles / day (+ long trips) and now is driven about 40 miles / week (+ long trips).

1995 Chevy Suburban, currently at 150,000 miles, Prior owner had transmission rebuilt prior to 100,000 miles. While towing my 18ft camper trailer on a recent trip every time I started off from a stop I had to really push on the gas to get going. At first I though the emergency brake was on, or I had a flat tire. I then noticed the automatic transmission was not shifting when I had it in D. Checked the transmission fluid and it was full. The transmission seems to be stuck in 3rd gear. When I move the shifter to 2 it will shift down. Reverse is also still working. Am I in for a costly repair?

I have random power drop off (best description is a loss then a surge or something like a skip) when driving over 60 mph. If I let off the gas or floor it the problem goes away temporarily. No mechanic has been able to figure it out. Chevy dealer just says "we don't have any codes".

2002, Chevy, Suburban 1500, 4wd, 5.3L engine, 210,000 miles. Mass airflow sensor and both O2 sensors replaced last year in an effort to fix this problem. Original problem surfaced when the vehicle was shut down or running uphill and had about 1/2 tank of gas in hot weather. If stopped, the vehicle would not start until it had cooled down. Sometimes getting it onto level ground would be enough to get it running again. ( This accomplished by turning on the key and allowing the vehicle to roll back out of the parking place. ) If running down the road, getting to level ground after the stall, pulling to the shoulder and cooling the engine/waiting a few minutes and restarting the vehicle would work. This was before the above mentioned repairs.
Last weekend in 60 degree weather I was driving back from northern Michigan and as I headed up hill at 75 mph with the tank at 1/2 the vehicle did a high speed stall on me. Symptoms were: RPM showed 2000, but pushing down on the gas actually dropped the RPM no matter how feather-footed I was. This was tried several times. I turned on the 4 ways and moved toward the shoulder and at 50 mph finally got the thing to restart. The rest of the trip home was uneventful.
I had a 2001 Suburban with the same specs which did this same thing until a factory recall that got me a new fuel pump. I asked about the recall the last time my truck was in for service and they said it does not fall within the serial numbers for that recall. Fuel filter replaced about 9 months ago. Co-incidentally but not necessarily related is that my battery with less than 3 years of a 7 year warranty was draining itself in less than 2 days this last winter.
