Kind of misfiring

[oldskull]

Well its happened last year before winter. My car does sound strange, it was like fuel not got thru. Btw I always had e10 in my car only since last year I had to changed to e5. Btw when I got some strange thing when below 2000rpm, I had guess because of changed e10 so I got almost empty tank and I put e5 in it and drive a bit then it was ok. so in the winter last year the car stood still for 3 months and in March I started the car again and the problem came back and quite worse, so I changed spark plugs and still the same. but also tried to see if I run less cylinder, but take off sparks cable one at time and it seems good. then I tried the timing screw at tps and it was quite ok but still kind of misfire when I give some gas (above 2000rpm) so today changed fuel filter, it still same.
any idea? my last guessing is ignition timing and also might be injectors


EDIT: well after 2nd and 3rd check (with friends on whatsapp) seems like that the last cylinder not working and someone suggested to clean the injectors.

Best to do a compression test.
It will be relatively easy to work out if you know that you have good compression on each cylinder.
If the last cylinder is down, don't despair, it may be something simple.

You could swap around the third and fourth injector to see if the problem now moved to another cylinder.

It could be that the old fuel has gone off enough to show up any ignition problems.
Try looking at the plugs, once they are fouled they will need cleaning. Old fuel
will foul the plugs. Easiest way to clean the plugs is with a blowlamp.

thanks for the reply. I already sent the injectors to clean them. they will test and then clean them and I also asked them to replace the rubbers too.
hope it was the injectors problem but I will update here when they done and install them

Got my injectors back, it has been tested and clean. two injectors was ok, one was bad and the other one was very bad. So they cleaned and replaced everything except the bottom rubbers because they don't have in stock. So I used the old set and put back to my car. Now it run normal again. Test ride a bit so it solved the problem.
Thanks all for reply my post

Depends on when. It's holiday season at the moment, so I'll be out of the country next week. So maybe somewhere in August or September?
