#65 of 72 Throttle body repair gone bad to worse by jay1310

Apr 12, 2012 (2:43 pm)

2003 Chevy Trailblazer, 6 cylinder repair went from bad to worse:
I had to change out what apparently was a bad battery. Upon doing so, my car's system engine lights and Reduced Engine Power lights came on. I had it tested, and
was recommended to change the faulty Throttle Body. I bought a used one, put it on and now its still behaving the same, only now also I cannot shift out of park. Are these two related? I think I have a bad used throttle body, but now I can't even drive at 14 miles an hour to the shop. recommendations? Car just hit 112,000 and I did try to reset the computer several times.

I have a 2005 Chevy Trailblazer that I had bought brand new, and now 7 years later with 190+ highway miles, am looking at replacing the engine, almost have all parts replaced why not the engine right? supposedly cylinder 6 had no compression, got a second opinion, and was told pretty much the same thing, took it to dealer thinking they could just replace the cylinder only to be told that it can not be fixed (mind you paid off, no warranty) valves are clogged with oil residue, all sorts of other issues inside there on top of that, so was told best bet to replace engine, contacted GM to report issue as I can not phatom this from a Chevy, I have had Chevys in the past well over the 250+ mile mark, and never had to replace the engine, very disappointing and I am sad, upset and all the emotions that could go along with this type of issue.

I assume you mean 190K miles. With that many miles I'm not surprised GM didn't respond to your satisfaction. Anyway, I don't know why anyone would want to with that many miles, but your best bet is probably to get a good used engine and have it put in.
Did anyone actually find out what was wrong with #6 cylinder? Bad valve? Hole in the top of the piston? Cracked block? Anything?

Did the map sensor and mass airflow sensor fix the problem or is it still occuring?
When we use the electric windows we get a reduction in engine power.
Thanks Rich

I have had the same clicking noise (I do believe) for years. It is just the fan clutch trying to engage/disengage, so my mechanic says. It has not affected my engine power, nor has given me any trouble except the aggravating click.

#70 of 72 Dies Randomly by help_me3

Jan 13, 2013 (6:17 pm)

I have a 2003 Chevy TB with 100,000 miles. Over the last couple of days my car will randomly die while I am driving. There is no check engine light or any clue as to what could be causing this. I have only owned the car for 3 yrs. and already replaced spark plugs, alternator, cat converter, starter, driver's side window (that was a weird one), and put a new (used) engine, and most recently fuel filter (hoping that would solve the problem)!! I have no code to check and nobody really knows what it could be. Any ideas??

Worst case id say fuel pump. I bought a 2006 that had a cracked flot in the fuel pump so the resevoir was emptying out at stops and right hand turns couldnt figure it out till it was low on fuel and kept doing it. Fixed my truck.
