Re: hesitates, jurks or stops at times when slowing or stoping or starting out
ASIDE from verifying all tune-up items--air filter, spark plugs, plug wires, throttle-body cleaned of deposits, IAC, PCV and EGR functioning properly with no excess carbon deposits, O2 condition, fuel pressure/filter condition, cranking compression, etc...
...you're going to get Schurkey's Perpetual Advice: You need a REAL scan tool that gives you access to the data stream. Reading codes is the very beginning of ECM diagnosis. Best would be to record the data stream so you can "play back" the data for a second or two before the stall or misfire. Then you can study the commanded fuel rate, the O2 readings, IAC readings, and all the rest of the input/actuator activity leading up to the stall or misfire.
I've seen engines stall on turns because the wire harness was being pulled due to excess engine rock because of a failed motor mount. The wire harness connector would break contact when the engine rolled to the side. Anything is possible. You might verify that the MAF is not faulty.

Ten trillion to start with, increasing as needed from there, PLUS compensation for the sickened, and "wrongful death" settlements for the families of those who didn't survive. END trade with Communist China.
