I posted in the other thread about the tour jerking. I've still got the problem and it is seeming to get worse.
I've got Autolight Double plats in it now and have always used them. I don't believe that is the problem. I pulled the three front ones the other night and they looked fine. The only thing I saw was a rust looking color on the white ceramic part of the plug. I believe that is normal but I'm not sure. I've tried looking up what different things attribute to plug failure but the only pics I can find are of the tips of the plugs in illustrations.
Anyways, I think this is a common problem with the tours now and I would love to find out the issue. I'm no expert and would love some help also.
I've recently cleaned the EGR passages and throttle body plus replaced the DPFE. I'm cleaning the MAF tonight to see if that could be the issue. I'm wondering if this could be the EGR or even a clogged cat.
Help!
