LEXONDUBZ Posted April 13, 2007 Share Posted April 13, 2007 I bought this 1991 ls400 for cheap because the starter was out. i replaced the starter and she ran fine... except for a leaking water connection tube. <_< I changed the gaskets and after putting everything back together, now the engine has a terrible miss! i checked everything from the injectors to sensors to ... well everything! the numbers 1 and 7 cylinders seem to not be working... i unplugged the injector plugs and the engine still runs the same. i swapped plug wires, injectors, plugs and it still runs the same! has anyone run into this problem also ? any ideas? am i missing something here or overlooking something? HELP PLEASE! :cries: Quote Link to comment Share on other sites More sharing options...
