Weird Issue..please help My car has been dropping rpms when I come to a stop while driving..so much that it almost stops running (around 200 rpms). Ive had this happen before and the remedy was to change the O2 sensors (Long Tubes dont play well with others) so thats where I started. I replaced the 02 sensors and took the car for a test drive and as soon as it heats up to normal driving temp, it starts droppings rpms again when I slow down. So today I started the car in the driveway to check for possible exhaust leaks, plug wires, MAF, filter, all of the usual things and the car ran fine for 30 minutes...it idled right at 600 Rpms. Then I put the car into Drive and it dropped to 500....and when I turn the steering wheel in either direction it drops to 300 and then returns to normal...does anyone have any idea whats going on?
Thanks

I second the leak idea. You are getting unmetered air into your system some how. As you turn the wheel and go in and out of P/D you are just going thru different Air tables/ loads/ temps. Have you done an intake swap, bellows/ lid/ TB on/off lately? PCV/ Vacum lines?
