RE: CHECK ENGINE light blinks during acceleration.
thats very bad, if it is misfiring that bad the blinking light means engine or cat damage will result.severe misfires and spark knock will melt a piston and burn valves. it is most likley a tune up issue, but find out what cyl it is by the dtc, autozone pulls codes for free. p0300 is multiple cyl miss p0301 is cyl 1 an through toop0308 is cyl 8 misfire. whan the plugs are removed is any of them are white and crusty, that is coolant and either a headgasket or cracked cyl head.
