A Flashing Check engine light , is A Random Multiple Misfire fault ? probably fault code P0300

can have the computer scanned & retrieve the fault codes ?

it is not advised to drive if the light is flashing it will cause internal engine damage

Most likely you need spark plugs & ignition coil

what is the mileage ?

and has it been tuned up ?

Please let me know

Thank You

was plugs & coils changed ?or just plugs ?

Plugs and wires

1- first you need to check for vacuum leak , you can do that by spraying starting fluid on the intake on cold engine, if the engine surge up in rpm , then you have a leak

2- fuel pressure test : 56- to 62 psi

3- you have changed the plugs & wires but did you change the ignition coil ? i sent you a picture of it

I replace evap vent solenoid light still on. Reading codes p0446 p011 and p0113
Customer: replied 4 months ago.
No coils
Expert:  Chad Farhat replied 4 months ago.

well that changes things , there is fault codes before the p0300 , that we need to address before like p0011 ,p0113 ,that you just told me about

clear all these codes and see what comes back first & let me know ?

Chad

that was one of the codes
Customer: replied 4 months ago.
The flashing just started today I drove blinking about 15 minutes top
Expert:  Chad Farhat replied 4 months ago.

you always start withe the first codes, so p0011 & p0113

so cam sensor & also the air intake temp sensor ,code p0113 ,could cause these issue, i changed a lot of them\so replace those

and lets go from there .

also make sure the spark is good on all wires coming from coil .

make sure the air intake breather hose is all in place and no vacuum leaks visible.

Please let me know

Thank You

Hey Chad, good morning. I have not bee able to get my car to the shop but I did realize that I had the codes incorrect. I located my last emissions test and the codes on there read P0113 and P0446. I am afraid to drive while light blinking and misfiring so I am having a mobile mechanic come to me. Thank you so much for your help!!!
