Engines - Chevrolet - Trailblazer :: 2002 - While Slowing Down Feel Like Engine Dragging?
Jan 29, 2011
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.

We own a 2005 Chevy Trailblazer, 8 cyl, 150K miles. Since July 11, the transmission has been slipping into neutral, usually when slowing down. This happens anywhere, and usually in slow (so far) traffic. My husband has been able to get the car to drive either in D3, or has been able to get it back into Drive, and the car just drives off like nothing happened. This usually takes a few minutes of turning it off and on, and shifting gears. Today he drove it in AWD, and it was fine (so far). He normally drives it in 4WD. They have been unable to duplicate this problem and, because there aren't any codes, cannot tell us what's going on. Needless to say, I've had it.

Wife's 2002 model, 104,000 miles on vehicle, but recently developed a tat-tat-tat noise when first turning the key. Sounds electrical. What may be causing the noise?

2002 Chevy Tahoe Z71 ... When I first turn my car on in the morning (or after an extended period of time - i.e. the car has completely cooled down) it makes a clicking / ticking noise that appears to be coming from the engine area. It lasts approximately 10 - 12 seconds and then simply goes away. This happens consistently. I recently had it serviced end-to-end: belts, plugs, total tune-up etc.

I have a 2002 trailblazer that will start fine in the morning and after it sits for an hour or two, but once i start it and run it for over ten minutes and i shut it off when i try to re-start it, it will crank but won't start. the dealer cleaned the throttle body and injectors, check the fuel pump for presure and it was fine,and they got no error codes?????? I've read that in can be the ignition switch??

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 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?

When turning in both directions, front end makes a CHEEP-CHEEP-CHEEP-CHEEP-CHEEP sound. Frequency increases when speed increases.Brakes are NOT engaged when this happens. Goes away when coming out of turn.
I am sure the problems could be multiple, but what is your first thought? Not that it matters, but its a 2002 Chevy Trailblazer.

This make and model is the same as a Chevy Trailblazer. It has 124K miles on it, when it's cruising, there is no weird noise from the engine, but when I give it gas at any speed, there is a distinct sound coming from the rear of the engine. It sounds like when you put a playing card on your bike and the spokes hit it, but faster. The more gas, the louder the sound. It's gotten progressively worse lately. My first thought was rattling valves, but I'm not sure. It also sounds like a hole in a vacuum hose or something. With the hood up and an ear to the engine, the sound is definitely coming from the engine, not around it, and toward the rear.

Trailblazer 2008. This has happened 6 or 8 times. When fuel tank is 1/4 full or less, decelerating downhill from 50 mph to make a right-hand turn, the engine stalls as I reach the turn. Of course I lose power steering and brakes.
If I stop in that downhill position, the fuel gauge reads ZERO but the Low Fuel light is not showing. Turning the key to restart does not restart the engine but if I roll to a flat piece of road or to an uphill position, the engine starts immediately on turning the key. The fuel gauge continues to show ZERO until I turn off the ignition completely and restart. Then the fuel gauge immediately returns to indicate 1/4 full.
No warning lights of any kind show on the dash. There is no question of the gauge showing a false 1/4 indication when the tank is actually empty, since I can drive for 30 miles after the incident while the gauge slowly drops lower until I fill up again with gas.
SOMETHING tells the engine it has no gas so it stops. No stutter or indication of fuel starvation. Simply an engine shut-off.
I tried to reproduce the effect immediately after it had happened by turning the car round and retracing the route, but it did not happen a second time at that location, but it did repeat a few hours later at another intersection.

The ac condenser unit will click every 7 seconds followed by a 3 to 400 rpm surge for 5 seconds or so, drop rpm then repeat. Belt looks fine, no slipping, new plugs a month ago, newish air and gas filter, does it in neutral or drive, read many ideas from low or high freon, iac, throttle body cleaning, o2 sensor? no codes thrown. Maybe coincidental but was discussing o2 upstream sensor recently on this board. The car experiences the same symptoms while driving.

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?

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.

I have a 2006 Chevy Trailblazer LS/LT 4.2 liter 2wd. I have been trying to get it smoged, but can't clear the code. P0171 - Lean Bank 1.
I've been having a parts throwing contest with it, but it has been winning and my wallet is losing.
I have changed the air filter, cleaned the MAF sensor, changed both O2 sensors, changed the secondary air valve and relay. I've done the carb cleaner spray test around the intake and vacuum lines, with no spikes in RPM.
Most recent try was a couple bottles of Techron concentrate with premium chevron gas.(still waiting to see if the code hits again)
Next steps are checking the intake bolts(to see if they are torqued) and intake gaskets, check for exhaust leaks at the exhaust manifold, and checking the MAP sensor.
Freeze frame data from the most recent hit on the code is below.
***Fuel system 1 - CL***Fuel system 2 - NA***Calc Load(%) - 30.2***ECT(deg c) - 48***STFT B1(%) - 3.9***LTFT B1(%) - 22.7***MAP(kPa) - 33***Eng RPM - 809***Veh speed(km/h) - 0***Spark Adv (deg) - 10.5***IAT(deg c) - 20***MAF (G/s) - 5.82***TPS(%) - 15.3***Air status - NA.

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!?

I have a 2002 trailblazer with the V6 engine. while driving it will say on the message center POWERING DOWN. the engine shuts off and after coasting to a stop its like the battery is dead. It wont shift into park and the key cant be removed from the key switch. thinking that it was a battery or alternator problem I had both replaced. And it done the same thing the last time it was driven. Had it towed home, connected a battery charger to it to boost it and it allowed me to cut the ignition to the off position and remove the key. What could be wrong with it?

2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higher rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to work for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on.

I have a Hyundai Accent 2002 which has 126k miles on it. Overall the car runs well without any trouble. Recently I am noticing that if I suddenly slow down (like taking an exit from interstate or sudden traffic so that speed reduces to 30 mph from 60 mph or so), the front of the car starts shaking. On a very few occasion I have noticed that the check engine light comes up for a few seconds and disappears. At the same time car looses it's acceleration power. However, as soon as I slow down further (close to stop) everything starts working fine without any issue. What could be going wrong? The car is due for a timing belt replacement around 130k miles .

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?
