hello brickers,

here's my dilemma...my 1990 240 has been starting hard for about 4-5 months...i brought it to my independent Vo mechanic and after a process of elimination (it got to the point where it wouldn't turn over due to not starting it for four days over the winter) he told me - after charging the battery that he cleaned the impulse sensor/crank position sensor (same thing), that it just fired up...this worked for a week or two but unfortunately the hard start is back... the same mechanic put in a new c.p.s. last august...he said it is still under warranty...does anyone know what else could be causing this? and, should i get a new c.p.s.?

all help is greatly appreciated...
