Hey guys, help here please,

Ok, so the cars starts fine, And seems to drive fine as you accelerate, but once you stop at a light or sit in traffic you start feeling this hiccup every 4-6 seconds. I think I know what it is but if any of you experienced this before and has anything to give me before I strart trowing parts, please let me know.

3 months ago I change the coils and spark plugs (cheap coils from amazon, good ngk plugs) so I went cheap on the coils and I think thats the reason of this. I still have the old coils that were still fine, I think. I'm going to try put those back and see if car runs fine again, then I will buy the OEM coils... Should I buy the plugs too?, probably yes, ugh...

 

No need to buy plugs unless they are counterfeit as well as coils
Would like to know more info:
what is the mileage of the car?
what was the brand of the coils?
is your CEL on?
Can you change coils 2 at the time instead of all at once? (I need to know how many replacement coils are failing.
I am now changing original coils with newer model Hitachi from Autozone (made in Japan)
one by one each month The newer coils like OEMs (p/n ending with -S01 instead of -003 are equipped with the vent hole on the back).

 

Thanks doctorj, sorry it took so long.

I got rid of those crappy coils and got my money back from the seller. The problem was the coils.
