My car just started have rough idle and driving problems (continues to have
miss under accelaration) this past week end. The car has 140,000 miles and
I just had the timing belt replaced 6,000 miles ago. I just replaced the
dist. cap and roter along with new plugs and  ing. wires to try and fix
the problem. The idle improved a little but is a long way from fixing the
problem. I just put a new fuel filter in today JIC( not expecting to fix
problem it just needed to be done). I'm not getting a check engine lite so
I'm kind of lost on what to do next. I've thought about changing the ing.
coil but I hate to throw money at something it does not need.  

Thanks,
JT
