i went started my car today and it started find and when i got to a light it started to jump and while i was pressing on the gas pedal it kept jumping like it wanted to kill. i put it in park and just cranked it up and while it was in park it was just fine but when i put it in drive it started jumping. i stayed in drive for a while with my foot on the brake and it kept jumping but at times it would start acting normal but it would start jumping again soon after.also it doesnt it now while its in park. what could be causing this do i need a tune up or could it be the fuuel pump...also it snowed not to recently and rain the other day while it was cold could my car just need to be warmed up...i was told that my spark plugs are bad will changing them fix this problem?
it is a 2000 mitsubishi galant with 195k miles on it.
Will changing my spark plugs fix this problem?
No it won't and it won't fix your atrocious English either. Reading between the lines and the very bad grammar I think that your idle is too low.
It is adjusted automatically by the computer. If your idle speed is too low it is because of a faulty or dirty Idle air control valve (IAC)
Will changing my spark plugs fix this problem?
do a full tune-up.....plugs, wires, filters, fluids....ect........but usually plugs and wires need to b replaced...
Possible causes......
Fuel pump/filter/injector
Throttle position sensor
Throttle cable sticking
Idle air control valve
Mass air flow sensor
Oxygen sensor or cat problem
Take it to Autozone and have an OBDII scanner put on it.
Plugs and wires will probably fix it. Good luck.
