My vehicle misfire in 4th gear to 4 thousand revolutions

My friends, bro, no, I want to get information about a subject My vehicle 207 makes a short misfire as if someone is holding back from behind when 4 thousand cycles pass in 5th gear.

I think it is from the spark plug or coil. Firstly, the spark plugs can be checked.

I haven't gotten it yet, but my first job is to make them look at it, bro. Is there a big expense

you are welcome my brother 307, 4 spark plugs 60 tl coil and 250 tl around i dont know your vehicle but i still want to spend unnecessary spending consult a master, but the masters are trying to find out by trial and error, it is good to start from the cheap one. It happened to me when I changed the spark plug and coil, I was feeling a slight jolt when I was idling

My bidet throttle supply vehicle is gasoline normally nothing is normal, sometimes it fails the brain, does the vehicle protect itself, did it happen, gas does not eat, 2,500 cycles does not pass, then the contact closes and returns to normal after waiting for 5 minutes.

If the throttle is faulty, it can make a room. But you have spark plug and coil check, it is likely that these two parts will be. And how many engines do you have 1.4 or 1.6?

1.4 trendy 75hb gasoline

you will probably find 15 spark plugs. you have to look at the coil, your coil is very expensive. Replace the 290 TL spark plugs first, then check the coil, the last throttle remains. If you want, you can have it cleaned and adapted. there may be a possibility of improvement.

Ok brother, thank you so much for your suggestions
