Accent 2008
 

i have had a boggy problem for months and cant find the problem i changed the injectors the coils the plugs cleaned all the sensors and no change at all at low RPM like under 3000 when its cold it sounds like it wants to stall when hot its boggy from time to time like one min its ok then 2 minutes later its boggy

Is the check engine light on? if so what are the codes?

Even if you have no codes you can do the following:
Make sure all electrical connections are clean. Check the battery cables and don't forget the ground connections.
Have the battery and the alternator tested. A bad alternator can cause all kinds of wonky things.
Check for vacuum leaks. Cracks in hoses can open and close when the engine moves a little.

check engine light on yes as for codes i dont have the tool for that so no idea. but il go look at the grounds and get the alternator tested the rest i already looked at

Olivier: I don't know where you live. But in the US and in Canada most auto parts stores will do a scan for free. Having the codes will help a lot.

in canada but here where im at they charge 40$ to do it but i guess my suffering ends now the car wont start anymore and the coils are no longer getting fire so i might just scrap it

I would buy a code reader. You'll need it for your next car as well.

this is what it sounded like when it did work im posting it anyway so if anyone can help it might be useful for future members

Not to rub it in or something. It just reminds me of this:
