I would suggest trying to find a way to scan your blazer with a scan tool that will show code history. it is obviously not a hard code if the light goes away but best to correct anything before it finally fails.

Need to check for computer codes to be sure. A common problem is when accellerating up an incline, the fuel system can run too lean causing a temporay code to set and by easing off the gas pedal the light should stop after a minute or so

2001 chevy blazer 4x4 check engine light flashes on highway no codes?


If it blinks and goes away, it is a "random misfire" that culminates before the light begins blinking. Sustained misfiring will result in a code, and the light staying on. If the light blinks and goes away, the issue is intermittent. Your problem usually occurs under acceleration or heavy load. The issue can often be solved with new spark plugs, though it could also be dirty injectors. The injectors on that vehicle are infamous, however I have been able to fix your problem with repeated use of highly concentrated fuel system cleaner. I use at least 3 times the recommended concentration of whatever cleaner. People rave about Sea Foam. I have used it and it works -- though I can't say whether it worked better than other brands I have used. I have owned 3 Blazers and 2 S-10's, including my current 2001 Blazer LT.

After driving my car 2006 chevy impala for about 20 miles the dashboard warning light oil pressure low stop engine and the oil warning light appears, but if step on break or slow down it goes out..wha


Verify that the engine has the proper amount of oil. The inertia from accelerating may be moving the oil in the oil pan away from the sensor and causing it to send a signal, then when you slow the oil levels out and the sensor go's off. I've had this happen alot with a taurus that I owned. The simple solution was to top off the oil to the correct level and the sensor did not come on again (until it ran low again, had a leaky oil plug on oil pan).

I have a 1991 chevy blazer S10 4x4 was driving on the highway and very bad shaking happend then slowed down for awile.. shaking went away but comes and goes! notice trans fluied coming from both ends of...


You stop using the vehicle NOW

COMMON SENSE

It will have to go to a repair shop

I would suggest a local trans shop, first

It could be a leaking seal,but one trip
down the street, and you could destroy
the drivetrain in a hurry, if your fluids are gone

The servicd writer suggests throttle control maintence every time I take my 2002 Escalade in for service. The car has 38000 miles on it, does it need that kind of service?


No service required unless the engine is idling to slow and stalling at red lights. This maintence is only requied on a as needed basis. Idle speed should be 550 to 650 rpm.

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,

Rattling noise


I have a 98 blazer that makes similar sounds but it's pieces of the dust shield off the rear wheel assembly that got down inside the brake rotor. Only happens when the truck is going forward
