is the check engine light on? If it is on, did you check to see what your codes are? you may need a scanner to look deeper into your problem.

If you get fuel too far up into the filler neck liqu

are you checking it with your headlights on or off? I think it's on with the dash illumination. If it's not on but the parts of the dash illumination come on I would look at the wiring to the individual light. There is no fuse in the light socket itself. And there isn't a fuse solely for the ashtray light. Should be powered up with a yellow wire from the dash illumination circuit and grounds

Check spark plug wires are going to the correct spark plugs.... all of your problems sound like the firing order isn't correct. Check even if you are sure your sure! Good Luck

Awesome advice. It's nice to know that even a tech that is having trouble diagnosing a problem has some place he can go to bounce ideas and seek advice from other certified Tech's.
