Thanks for the quick reply Steve,
First, a couple of things: When I originally went to the dealer to replace the 0420 manifold- the firewall side, somehow the techs (@ Hollywood ford) pulled a 0430- the front. I have never pulled this code with my scanner. They replaced the front and cleared the code. I have this documented on the service record. Now, this whole time I was thinking "OK, I'll bring it back when it spits out the 0420 again". Which it did within a week. The rear was replaced as well- also documented.
So as far as I know I've got 2 new manifolds (new as of Nov. '02). Is there something, ANYTHING, that I could be doing that's F'ing up that rear manifold?! I mean c'mon, TWO bad rear manifolds in just over a year?
As for the 1151- I'm just glad it's not that b*tch on the rear again! My knuckles were shredded and bruised for weeks after that!
Thanks again though,
-Chuck
