    hey- dont apologize for your english. it's 10 times better than some of the members here who are from the USA

    you said your check engine light came on- have you been able to get the code to see what it's for specifically?

    There is no way to help you unless we know what the code is. So you're misfiring at 5k RPM?

    Try changing the fuel filter. Maybe the bad fuel clogged it...idk.

    did you reset the ecu after the fuel problem? (unplug the battery for a while)

    it really would help to know what codes are in there, take it to a local shop and ask very nicely and they might do it free

    Most shops around us like advanced auto will read them for free, they just loan you their scanner for 5 minutes.

    P1087 = LH TGV circuit high input
    P1088 = RH TGV circuit low input

    Something is wrong with your TGV's.
