so my 1995 contour lx with 68k miles auto has the shivers well rough idle is more the term i think. like when stopped in drive my rpms will jump from 100-750 to like 300 then back up when it drops the car shakes i read on here someone else had same problem and he used new plugs and wires to fix i ordered the 9mm ford racing from zxtuner and bought autolite double platinums at autozone i should get later this week i also bought a new tps(throttle position sensor) but the dealership cleaned the old one torqued the bolts back on and stripped the heads so next day i have off i have to pull em and buy new ones. anyone else have anymore ideas to fix problem?
