this could also be the tps, needs to be set under 1 volt like .98 .99 if this is out the car will idle up and down an sometimes stall this is on top of the thottle body 2 srews need a multimeter to ckeck

spry carb cleaner where you think your vaccum leaks are when the car is running.The idle will change if there is a leak!

Don't feel alone man I'm going through the exact same problem!!!!!!! I changed my tps and it helped but didn't solve the problem I'll hook up a meter and check that I haven't done that yet I'll let you know how it goes

quickest way is take it to a shop that has a smoke machine
