2003 chevy trailblazer service engine soon light


If the service engine soon light is flashing, it means the computer has detected an engine misfire with the potential of catalytic convertor failure. Don't just tune it up. Bring it somewhere they can read the trouble code. Sometimes it will designate which cylinder is having the problem.

2003 Chevy Blazer idles low and rough and accelerates rough until about 25 or 30 mph. Afterwards, it drives great, but the service engine light continues to flash.


Flashing service engine lights are very bad, means there is a problem that can potential cause harm to the engine. Sounds like you may have a bad coil. Take it to a place like Autozone which can check the check engine light. They'll give you a print out that will give you a better idea on what's going on. If it's a misfire on a cylinder or two, check plugs and coil, also could be an injector.

My 1996 chevy blazer will start but it wont excellerate past 15 miles an hour and my engine light is flashing.


You will not be able to go any faster when the engine light is flashing the computer of the vehicle has gone into protection mode.It will not allow it to go any faster. When the light is flashing it means their is a potential danger of damage to the engine or transmission and the computer goes into protection mode.You must take it to a garage and get the computer scanned and the repairs made and the computer reset after the repairs are made. Do not drive this vehicle at all it would be safer to have it towed so you don't cause more damage to it

2000 chevy blazer starting issues


swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.
Regards,

Wow, I just went through the same problem and guess what it was a clogged converter and a bad oxyegen sensor. The garaged fixed it up for me by putting an eco converter on it and a new O2 sensor. I have a 2003 Chevy Impala,V6 3.8 engine. Good Luck!!!!
