Change the fuel filter
my Chevy blazer power seat on my 1996 Chevy blazer isn't working
Could be a faulty spark plug or spark plug wire.
My guess would be wheel balance.
check your oil lol
try checking your mass air flow sensor or just change it.
your heater core is going out, you need to replace it before it ruptures.
AnswerYou need a tune up. You know plugs, wires, distributer cap maybe an oil change. You also have to change the pcv valve, it makes a huge difference when you're getting up in miles.
if u run your blazer low on gas quite a bit you probably burnt up ur fuel pump which is in the tank not a fun job. Good luck
This is caused most likely by the transmission is going bad. Need to repair asap
Check the headlight switch, if not it's probably a fusible link in the headlight circuit.
Probably a rotted out brake line sprung a leak, check the brake fluid reservoir.
