mfa_mad_pig Posted July 6, 2014 Share Posted July 6, 2014 So I've got an 84 EA81 wagon and it idles really rough. I recently did a weber conversion and changed the head gaskets and and there are no vacuum leaks, it still idles rough. What could be causing this?

mfa_mad_pig Posted July 14, 2014 Author Share Posted July 14, 2014 Triple checked and can't find any vacuum leaks. Also has a new PVC valve. Idles rough above 900 rpms and won't idle at all below that. Anyone have any ideas? Link to comment Share on other sites More sharing options...
Dee2 Posted July 15, 2014 Share Posted July 15, 2014 time for a tune up ? Link to comment Share on other sites More sharing options...
mfa_mad_pig Posted July 15, 2014 Author Share Posted July 15, 2014 Forgot to say already have new plugs, wires, cap and rotor, and fuel filters. The tach jumps up and down at idle also. Link to comment Share on other sites More sharing options...
Hsoj Posted July 16, 2014 Share Posted July 16, 2014 Did you check the float? They get bounced around in shipping quite a bit and can get damaged. Truthfully, I've only installed two, but both were off. Link to comment Share on other sites More sharing options...
naru Posted July 16, 2014 Share Posted July 16, 2014 Forgot to say already have new plugs, wires, cap and rotor, and fuel filters. The tach jumps up and down at idle also. In that case,remove the cap and see how much sideplay the distributor shaft has. Should be very little. Link to comment Share on other sites More sharing options...
mfa_mad_pig Posted July 17, 2014 Author Share Posted July 17, 2014 I rebuilt the weber so I think the float is probably good. Checked the distributor and there definitely is some play when I wiggle the rotor. Not sure how much is too much though... Link to comment Share on other sites More sharing options...
naru Posted July 17, 2014 Share Posted July 17, 2014 Anything more than barely perceptible is too much. The reluctor air gap is only .020" maximum. The jumping tach is a dead give away that you need new distributor bushings or a new disty. 1 Link to comment Share on other sites More sharing options...
mfa_mad_pig Posted July 17, 2014 Author Share Posted July 17, 2014 The tach only fluctuates a couple hundred rpms so I think a rebushing should do it. Link to comment Share on other sites More sharing options...
