now im canadian so to me its around 120-130 kmh but i posted 70 since its mostly americans on here, heres the problem, if I am on the highway and I need to pass a semi or someone in a work truck filled with unsecured landscaping equipment I need to go well above 130kmh to get passed him comfortably then slow down to the speed limit again, heres my problem everytime ive tried to do that, once i hit around 130kmh my car jerks and slows down i lose alot of throttle response my check engine light comes on, and i cant go above 80kmh until i pull over turn my car off for a minute then start her up and keep going, some things to note, my fuel pump relay plug is on its last legs its pretty fried, relay itself is good, the transmission needs servicing, i just cant afford it, and previous owner said its a 3:50 gear in the back, any thoughts as to what it might be will help
