I just got the car last week and I think the plugs and wires are the original ones on the car.
Im thinking maybe that’* the problem or maybe a throttle position sensor.
Any ideas on what might be the problem???..
well it isnt your throttle position sensor cause i just changed one of those and your cars rpms would be of the wall when sitting at a stop light or in N or P the tach would spool up
and it might be your spark plugs
one way to find out is at night when there is a little bit of light left take your car open the hood (while engine is running) take a pair of heat gloves and put them on and then one buy on remove each spark plug carefully make sure though that you keep in close enough that it makes purple or electric current
for your fuel injectors( that is probablly your most likely fix) take out the fuel injector rack and find out if there is any bad ones and if there is replace them and put the rack back on
do try these and tell me what happens
