got a 98 sohc and i changed the altenator and the cars shakes and idles extremely low, around 100-200rpm


any advice?

 

there should be an adjustable screw on teh throttle body - to adjust the idle revs, just turn it to let more air in.


but thats from what ive heard, so i dnt really know
..cmon experts help this guy out

 

the bottem line is 500rpm

try messing with the iac valve; or you can reset your ecu by pulling the battery fuse or disconnecting the battery for 15 secs, i think? For a little while mine shoke at around 500-600rpm, but eventually fixed itself

 

so far, i think my car needs more ground and more power, maybe a capacitor or another battery........i added some ground wires, now it idles around 400-500, but still shakes sometimes

 

Bad plugs? I would put the old alternator back in and see what happens, something could be wrong with the new one
