Hello everyone. You have all be hugely helpful in solving my mechanical challenges, so I thought I’d test the waters again. When I got my van about a year ago the idle was ridiculously high, so one of the first things I did was adjust the idle screw. I turned it to the lowest setting—which felt a bit strange—but it has purred like a kitten ever since. I really only have two small problems at the moment, and they both seem to occur when I’m on the freeway. The first is that I often get a CEL code 71, a California specific reading that points to the EGR valve (gas temperature). I plan on taking out the throttle body and EGR valve, cleaning them both, and possibly replacing the TPS while I’m there. Seems like a good place to start, although I am a bit intimidated about the whole project. The second problem is that occasionally the Van hesitates when driving 60+ mph…just a little sensation where I press the gas pedal and the acceleration disappears. First time it happened was on a windy day and it almost felt like the wind was holding it back, but it wasn’t. I’m not sure if my catalytic converter is still doing its job, so I purchased an aftermarket bolt on just in case. I do get some strong smelling white smoke mostly at startup, and I think the Van does burn some oil (valve seals?). I thought the EGR would help address the upstream issue, a fresh catalytic converter would help downstream, and I’m adding some Bar’s Leaks Valve Seal stuff for the hell of it. My main question is does this sound like an okay approach and what else should I be looking for? Finally, there’s an intermittent “leaky air” sound that seems to be coming from the passenger’s side of the engine. It doesn’t in any way effect performance, but I’m curious to know if anyone might know what this is. Thanks.
