this scared the crap out of my wife, she lost acceleration, had to coast over while in rush hour traffic. Turned the vehicle off, waited a couple of minutes and it worked fine... there was not reason for any of this no rain, no reason, dry weather, not driving under any condition to trigger this.

Could this be a big problem?

it doesnt tel how

I am getting about 8-10 miles/gallon or maybe 180 miles to the tank and I can't figure out why. In the last 2 yrs it has gotten worse. The system is not producing any codes and I don't have any check lights on but I know my truck (I bought it brand new in '02) and the gas mileage was never this bad in the earlier years. I have had it checked out but mechanica can't finds anything even after replacing the fuel filters. I think it's a fuel pump going bad because the "empty" will come on when I need gas and when I start it later it will be off and the needle is a little higher. Slightly erratic gas needle but not obvious by any means.

conditioner was not working so well...I had the freon checked...and the fellow added some..but told me he thought the door controlling the air flow on the drivers side was stuck shut. I get air flow through the vents on drivers side...but no cool air. I suppose I need to investigate under the dash and see what i can free up. Any suggestions for what I should be looking at/for ?

Took it to O'reillys to ck the diagnostics and was told that it was the variable camshaft timing cylinoid- However I read that before changing this part to possibly ck the engine oil to make sure that it is not dirty!? I was due for an oil change two weeks ago and my change engine oil light has not come on yet- has anyone else had this issue with it being as simple as changing the oil? I get really crappy gas mileage (like maybe 8-9 miles to a gallon)- HELP! Love my Trailblazer, hate that the engine light is on and that my gas mileage is soooo crappy!

with the timing chain tensioner if any

Engine light on, OBD II Code P0128 and P0106.
Coolant temperature below Thermostat. Leak somewhere from the coolant line when the air-cont on. I just change the map sensor last week and reset it but now the engine light back on. Should I have to change the Thermostat?
I really appreciate any help...

Loud whining noise in the trailblazer,any ideas on what that could be??

The gas gauge still shows empty.

Fluid is full and not off color or burnt smelling.

where is the oil pump located

My AWD doesn't work, (4-high & 4 low both work) how do I fix it?

they told me could be kinked hose, and a bunch of other things, said couldnt pin point problem.

it worked fine untill i went to the beach

What services are included in a tune-up?

How many O2 sensors are on this vehicle?

If so, what can I do make it run a little longer until I can properly fix it?

this vehicle has rear air conditioning

When I am driving home from work at night with headlights on, from time to time they will just completely go out and not come on for a whole day sometimes. It may happen 2 to 3 nights a week and sometimes it won't happen for weeks and then just start cutting off again.

I have a 2005 trailblazer 4.2 6 cylinder that the enging needs rebuilt in. The main when out and it needs repaired. I would like a rough estimate as to the cost.

engine light flashing,car jerking CodePO300 replaced #4 coil. Five days latter doing the same thing again everytime you start it. Will this damage the cataletic converter to drive to mechanic 3 miles away?

i want to fix my horn myself without paying a high price to dealer repair shop. i understand there is a simple way,but must becareful of air bag comming out.

its for a 2004 chevy trailblazer 4.2 2wd.

While going up a hill I had the cruise on and lost power. The reduced engine light came on and the cruise has quit. I pulled over and turned off the motor and restarted and the the was out but the cruise still didnt work and then the light came back on after a couple of miles. It comes on everyday and most times if I run the air conditioner it sputters. I have learned to deal with the service engine light but I dont know what to do about the reduced engine power and the cruise.

When I move the air flow control to defrost, the tapping sound stops. When I move it to direct air flow to any other position (i.e., front vents alone or front and lower vents or just the lower vents), the taping sound returns. After a long (and annoying) time, the tapping sound eventually stops. Fan speed has no effect on this. A/C on or off has no effect on this.

It seems like a solenoid but I don't know. Anyone have any clue? I haven't found a repair manual that addresses this part of the air cooling/heating controls in the dash.

Thanks.

not sure how long this was going on had no warning lights or anything.

A mechanic found that my passenger side inner and outer tie rods are defective; he showed me the problem and I agree with him. The driver's side is not as bad but I didn't like it. He made me a quote to replace both outer and inner tie rods (Moog parts) and 4 wheel alignment for ~$1200. This seems about $300-400 too high. He has vehicle in shop now.

The clutch motar needs to mbe replaced. I think it might be to hard by myself. What are your thoughts? Does anyone do it on the side in Louisville, Ky?
