Timing is fixed at distributor and adjusted by the computer. Do you ever lose any coolant from the reservior or see any leakage. Lower intakes are a known problem around 90-100k leaking some coolant into the valley so fill that up and watch it. Read More...

Thanks for the help. I have changed the plugs, wires, cap/rotor, fuel filter and air filter. Guess that narrows it down. I have 103K on it. Driving habits are all highway averaging 75 MPH. Could it be a timing issue? Read More...

In drive thats correct. Many have a slightly rough idle could be from many things: injectors get buildup of waxy crap from cheap gas, cap/rotor, plugs, wires, fuel filter, sensors degraded (O2, MAF, temp, etc), vacuum leak, idle air control valve, clogged air filter, and each has to be looked at. Sorry no easy answer. Can relate to area, mileage, and driving habits. Read More...

Noise, Clanking From Rear End...Eikkk

Written by: peanutz2 on Oct 16, 2006 05:38 PM

I have a 2003 TrailBlazer and in the last 4 months I have noticed a Clanking noise that has developed from the bottom rear chasis area. I first thought it could have been a loose spare tire in the under chasis, but that isn't it. I took it into a Chevy dealership today, they say it's the rear Stablelizer suspension bar that is going out and both need to be replace at $310. ... Read More...

Re: PLEASE HELP 2003 Chevy Blazer 4x4 Bubbling Garguling noise. [jkev229]

Written by: repairdog on Jun 04, 2006 03:22 AM

Yes, and this is classic heater core clogging noise and the quick fix is to flush (which is cheap and easy) but the real fix is core replacement and thats pullng the dash so over $500 to get to the heater box. Dex cool and 4.3L Blazers design with the GM cap have had more problems than most other GMs. That 5/150 coolant ad is BS and if you search you will see the many complaints. ... Read More...

I had the dealer flush out my system an it still makes the noise, the crazy part is whenever ... Read More...

96 Blazer ABS Brakes

Written by: sierrablazer on Mar 10, 2005 05:11 PM

My 96 Blazer started making a chirping sound when the wheels were rolling, and the smell of brakes grew stronger every day for the past month. We took it to two mechanics who said nothing was wrong. Then, this week, I started getting all kinds of grinding sounds that shook the vehicle when I used the brakes, and they would stick when I started to move again. I took it ... Read More...
