    My car just recently started acting up, I noticed the rpms keep bouncing up when im in a complete stop or driving slow, most of the times it stalls..... I have changed the oil and filter, new sparks and wires, cleand the air filter the MAF and TB, and seafomed it, still nothing has changed, I know my cat was starting to get clogged, could that be the problem.

    I scanned and these are the codes I got.
    p0171,p0102,p01443,p0650.

    any help would be greatly appreciated.

    **** well I tried everything, I changed the cat, egr valve, fixed all the vacume leaks, replaced MAF, and changed the plugs and wires, turns out the fix was a new battery, my old battery was not giving enough voltage, which coused my Rpm's to bounce up and down and eventually stall......
    so hopefully this is the same fix for everyone else with the same problem.***

    I don't know if this matters but I forget to say that the Rpms starting bouncing back and forth between 500-1000 Rpms, if it goes under 500rpms it will stall

    ok guys I havent changed the egr valve, but I did find some vacume leaks, so do I just replace the lines or is there a way to plug them up or something.

    depends on the lines, some time you can get a way with just tapeing over the leak and others you just have to replace
