Recently had my check engine light come on and when i went to get it checked the codes were for misfires on 3 and 5 and random, had my spark plugs replaced and wires at pepboys. 2 days later the check engine comes back on so i take it back to pepboys and it more misfires they cleaned out my fuel injectors and the check engine light turned off and said i was all good to go, they said the test drove it and left it running for an hour without any issues, on my drive home once i hit about 45 mph the check engine light started flashing and my car began to jolt and then the check engine light became sold, after i panic attack and slowing down to 5 mph the light turned off. pepboys doesnt want to see the car again any help on whats going on im scared to drive it ---

When the Check Engine flashes, it indicates a major misfire is occurring. This can cause damage to the engine/catalytic converter(s). Take the vehicle to a shop that’s somewhere close and get this figured out. Because without doing so, can cost big money later. Tester ---

Pepboys doesnt want to see the car again ? Tell them you want your money back then as they did not fix the problem . If this has coil on plug then it is possible you have bad coils on 3 and 5 . I wouldnt drive it anymore than you have to in this condition. Find a good independant mechanic . Do not go to chains like pepboys, firestone , etc… Find an independant or go to the Ford dealer who will be more expensive . ---

when i brought it back the second time they checked the coils and said they were okay and and cleaned the fuel injectors at no cost because 2 days prior i payed for spark plugs and wires, but when i called and said what happend just after i left they said they dont do free work and everything should be fine, i called and filed a case with pepboys so hoefully i can get some help
