300CE engine miss
I changed out my valve stem seals yesterday.
When I went to start up the engine...it had some troubles.. so I shut it off.. it seemed one spark plug wire wasn't fully engaged. Took care of that. Start up again... seems like a slight idle issue or miss. I look around and notice a vacuum line off. Put that back on. Still not idling correctly, so I am thinking a cylinder miss. Maybe a bad spark plug wire. I'll be out in a few minutes looking for any other vacuum issues.. any obvious way to tell a miss from a vacuum issue? EDIT: took it for a test ride... has to be a miss.... when it cools, i am going to pull one wire at a time and see if it will crank. i figure cranking on 4 cylinders will be real rough.. when it cranks the same.... i'll have my culprit... if this doesn't work... i guess it will be vacuum SECOND EDIT: I pulled the wires one at a time... the engine seems to respond the same, no matter which wire is pulled. Stumped.... I am now wondering if a badly seated stem seal could cause the roughness?
