Recently replaced spark plugs and wires on 02 SL1 with 209K miles. Was running rough, rough and high idle, almost died on me driving home one night. After replacing everything, car still wouldn't start. Spent some time on the forums and some suggested a leaking intake manifold gasket, so I changed that out as well as the coolant temperature sensor. Still it won't start. I am getting good spark at the plugs (coil arcs across the posts when plugs wires are off).
Really not sure where to go next with this. I can hear the fuel pump hum when I turn on the ignition, and I get a good spray at the fuel rail. Basically I turn the key and it cranks, sputters, and will almost catch, but then not.
What next?? Help!
