Check for a leaking fuel injector. It could be desperately flooding the engine under certain conditions...accordianman

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

do you mean crankshaft pulley? i dont know of a cam pulley on these.
if so replace the whole thing. the rubber on these go bad and rip away from the pulley. it happens. Just get a new one. should be a press fit one. may need a pulley puller. not the JAW type, but the 3 bolt type.
goold luck

sounds like there's too much of a load on the engine. try a complete tune-up.
