Check engine light blinks

I think for about $80** you can get a decent OBDII reader , the same as what you spent on parts you didn't need , now you have to read the codes anyways , and seeing as it's not running right you shouldn't drive it to auto zoo , there''s certain tools you should have if you plan on doing your own work

This means mis firing. Sounds like it's starving on fuel. Check fuel filter and fuel pressure. Still need to read codes to verify before throwing parts at it as it tends to get expensive

Blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can quickly raise the temperature of the catalytic converter to a point where damage is likely, requiring an expensive repair.
