Chevrolet - Trailblazer :: 2004 - Losing Acceleration / Service Lights On
Apr 23, 2011
I have a 2004 Chevy Trailblazer that looses acceleration. If I have the cruise control on it will the speed will decrease and then accelerate on level pavement. At idle the car runs fine. Could this be a fuel filter problem, an air flow problem or something else? Also the service light is on. I had it checked and the technician told me that the oxygen sensor on the exhaust needed to be replaced. I did that and the light is still on.

I'm a single mom and really dependent on my car for my job and my kids... I have a 1995 Chevy Camaro 6-cylinder, and I am having engine problems... in the mornings, my car starts fine, but if I drive more than a few minutes and turn it off, she doesn't want to start up again. It turns over just fine, but it sputters and refuses to stay started. After a couple of tries, I can get it going, I rev the engine, and a cloud of dark smoke (not blue and smells like gasoline) comes out. I also smell gas strongly when the engine idles after everything smooths out. Sparkplugs, fuel filter, oil, air filter, belts, hoses, all have been replaced recently, catalytic converter is only four years old, and car has 178,000 miles on it. What I may be dealing with? I'm also losing acceleration/power when I try to speed up...

I have a 2004 Chevy trailblazer. I got in to got o the store the other day and realized that my rear door speakers were not working. I checked fuses and none were blown. I have a line out splitter attached to the rear speaker wires behind the stock radio for my subs. My subs are still pumping, so that tells me that the radio is putting out signal to those rear speaker wires, but still nothing from each of the rear doors. I am curious if there is a simpler way to fix this aside from taking the rear doors apart to check the speakers. is it possible the radio is shot? what are the chances that both door speakers blew at the same time?

2004 Trailblazer 6cy. 2WD - has been experiencing a very rough idle, engine shudders - no matter how long it's been warmed up. Wants to stall off red lights and at very low speeds. Not throwing any lights yet - but the speedo is out ( a cam shift typical problem for this car) so I don't trust the console for lights. Worse when the heat or air is on. Rides fine with more gas/higher speeds. Definitely worse in colder temps but continues even after 40-50 mins of driving. I've heard a number of things, but can't afford to fix them all. I've heard plugs, dirty throttle camshaft, sensors, cam actuator solenoid, etc. All seem to have people who said it fixed and didn't fix the issue. Worried I'm going to stall pulling off a stop and rear end someone any day now. Where do I start!?

Symptoms- won't rev over 3000-3500 rpm's, upon acceleration (especially uphill) seems to struggle and won't accelerate much at all, seems as if trans changes fine. BTW, throwing no codes at present.
What I have already tried...new air filter, new fuel filter, had cat. check (was told stopped up but when removed found it was not and truck did the same even with cat. off), o2 sensor (upstream) replaced, battery disconnected to reset computer.
After reset of computer, runs a little better but still not good. Seems to start if you accelerate to quickly or when truck reaches around 40-45 mph.

I changed my plugs recently in my 2004 Chevrolet TrailBlazer 4.2l I6 with the coil on plug setup, and now it is misfiring and hesitating when I hit the gas. All the spark plugs have the proper gap and torqued down properly. I tried tightening down the ignition coils and on one I snapped the bolt. Of course my truck is staying parked until I replace the part which I have to order online. The only thing I can think of as far as the misfiring is not having a proper seat with the coils, my question is, how to get a better seating or if there are any other possible issues I could have over looked at all?

What are symptons of a "bad" drive shaft? Just curious because during a recent trip to the dealership for an oil change a mechanic told me I had one(I had mentioned I heard a noise that seemed to speed up and slow down as I drove-kind of a whirring noise). He arrived at that diagnosis by pushing down on the hood with enough force to make the vehicle(2002 Chevy Trail Blazer w/4wd) bounce up and down - there was a clunking noise. I haven't taken it in to have it looked at more closely, mainly because I am afraid of the cost. What's involved in replacing a drive shaft? What's the cost? If it is really "bad" will it break suddenly and cause an accident?

I have a 2005 v-6 and when I first start my car, its makes a real high pitch whining sound that will last for about 10 sec. before it starts to whine down.Then after that, its ok. It will not make any noise after that when I start it unless it sits for any length of time (6 to 8 hrs.) What might be the problem and If Its something I could fix myself?

I have a 2004 Chev Cavalier with a 2.2. Ecotec OHC. Lately the car has started to stagger on acceleration. Particularly when going up hill. The weird thing is, it only does it after it's been running for 10 or 15 minutes. Up until that time it runs smoothly. But when it happens it feels like the engine bucks. Or hiccups. If I stomp on the gas the car will either stall or kick in and overcome this. When I'm driving down the road at a steady speed, or when I'm sitting still the engine will buck in the same fashion. Not steadily--intermittently. Once or twice every fifteen seconds. But it's getting progressively worse.
Now if I launch out of an intersection the car might even stall. When this happens I just turn the key and she fires right up again as if nothing happened. No "Check Engine Light" or trouble codes showing up in my Scangauge. I replaced the fuel filter just as a preliminary measure but that didn't solve the problem. I had the fuel pump replaced a few months ago as well but that ws before this problem occurred. No other parts or pieces replaced. Fuel pressure regulator? Spark plugs? Injectors?

I recently bought a 2005 Chevy Trailblazer LS EXT 4.2l 6cyl with about 129k miles on it. The vehicle is excellent condition and has no leaks on the engine or transmission. I took it for a test drive before buying for about 20min and no issues with it shift or rough idling.
After having the SUV for about a week, I noticed that it has a slight rough idle at red lights and gets a little worse when the AC is on. Twice now in the past week the SUV begins to sputter at the red light and then shuts off. It doesn't do this every time and I have noticed it happens more when the fuel gauge is in between the quarter tank E line. My father in-law is having a similar issue with his 2003 Trailblazer, same engine and make and model.
I should also mention that no check engine light comes on or leave an ERR code.
Throttle body needs to be cleaned: We have done this on my father in-laws and didn't fix the issue.
Replaced the spark plugs: didn't solve the issue
Read that it could possibly be the APPS sensor under the gas pedal: Haven't replaced this yet
Tighten or replace gas cap: Have done this, didn't fix
Have the idle reprogrammed: Have not done yet.
Could possibly be a fuel pump issue.

I have a 2002 chevy Trailblazer that when you put it into drive there is a vibration.It does not do this in park or neutral. I have checked the engine mounts and transmission mount, and they look good. The vehicle has a little over 118,000 miles on it and the engine runs and drives great except for this vibration that i do not know where it id coming from. What may be my problem?

I’m hearing a horrible sound when I drive my 2002 Trailblazer. It has 250,000 miles and we have babied it since the first day we bought it. I’m hoping it will last another year. The sound I’m hearing happens intermittently. I took it by a mechanic, and of course it didn’t make the sound. It sounds like you are driving over rumple strips found on the shoulder of expressways. I then feel a “drag” and it goes away. What’s going on?

I have a 2008 Chevrolet Trailblazer. I have had 4 of these vehicles and have been very pleased. This latest one has 61000 miles and occasionally has a very strange vibration at speeds above 60 mph. It only happens occasionally and most often occurs at these higher speeds and worsens with increased speed (of 70-73 mph). The vibration is so alarming, that I will press my brakes to slow down, because it feels like the vehicle is starting to lose control. The problem is that when I press the brakes, the vibration intensifies about 3-4 fold! It feel as if the wheels are going to come off. It's a very frightening feeling. I have taken it to the shop and no one seems to know what it is. The tires are fine. Brakes are fine. Interestingly enough, if I lower the speed to 50-55 mph, the vibration lessens and eventually completely goes away.

About once or twice a month my 2000 Trailblazer dies immediately on starting. Will not start again for 10 minutes. After 10 minutes rest it always restarts. Never dies while running. Have had fuel pump replaced about five years ago. Condition has been occurring about that long though and has progressed from once each 3 or 4 months to its current rate. Can occur after setting all night or after having just run and shut down for a very short time. Natural assumption would be fuel pump but as it always restarts on second attempt after 10 minute rest is there any possibility it could be a computer malfunction that takes that long to reset?

The battery on my 4.2 liter inline 6 2008 chevy trailblazer is draining without the key in the ignition. I have checked the alternator, fuses, and starter with no luck. What might be causing this problem?
