Hey there ~ THANK YOU for the reply! And the verdict is....Mass Air Flow Sensor. Replacing it cleared the trouble right up. I thought all along that the Knock Sensor didn't seem like a likely culprit, but I am not a good mechanic....but the van seems to be running a charm and I can pay my friend off in installments - so al in all this van has been completely amazing when it comes to trouble. Bought at 95K and is now 160K with nothing but a Fuel Injector gone bad. So I can't really complain, and I won't. Thank you Tempfix for your time to type, I really appreciate it! Hope all is well - TH
