Weird missfire won't go away
Last week I drove to work and all was good...after work, put in the key and just got a hard CLICK and all the instruments went down. Key off. Key on. dash is back up so hit the starter and again, just a hard click then nothing. Got a jump and she started right up so I figured just a bad battery. When I went to drive home it started missing and shaking - especially above 2700rpm then everything started "flickering"... warning lights... everything. I pulled over (on the freeway) and had a rough idle but oil and temp were ok. Did the key-on, off, on, off, on trick to get my codes and there were a bunch!
Drove her on home but it was BAD! Some of the codes were 0303, 0353 and some others but the very last one was low voltage.
Replaced the battery at home and discovered that the brass neg cable end had coroded through and it had been intermittantly making and breaking connection while I was driving home! That explained the flickering. So I repaired the cable and replaced the battery and took it on the road to the parts store to turn in my battery core and clear the codes. It ran better, but still had a solid miss and the 0353 code for coil #3. I have always been so happy with this car and now it runs like crap.
I swapped coil 3 with 6 and the code still says 0353. I replaced the plugs.. no joy. This weekend I am going to check for voltage supply and trigger at the coil plug and probably buy a Haynes or Chilton.
