I would check the plug wires and the exhaust system.
If the check engine light is blinking , that indicates a cylinder misfire has been detected White smoke coming out of the exhaust ( especially when the engine is warmed up ) indicates that coolant is getting into an engine cylinder from a bad head gasket , a warped or cracked cylinder head
it could be the coil
Have it checked for codes. That should give you a starting point for diagnostics.
Wiring, vacuum line, exhaust restriction.
No, have it looked at by a professional.
95 s10 blazer has a miss and check engine light does not come on and exhaust smells gassy what could it be
the check engine light means you have something wrong with your emissions. theres something wrong with how your car lets out exhaust. There are sensers on your exhaust pipe that sense how much exhaust is being let out and how much unburned fuel is coming out. There is a computer in your car that senses that and try's to fix it. one of your sensers might be bad or you might have a clogged catalatic converter.
Propably needs a tune up. Plugs & wires. This vehicle is 11 years old.
The check engine light comes on when the computer detects a problem and sets a code. You need to have it diagnosed with a scan tool. The loudness may be an exhaust leak. the o2 sensors will pick up the change of exhaust gases and set the Check engine light.
