Today the 96 Neon has a rough idle and is hard to start. How can I diagnose this?

HELP!!!!!!!!!!!!!

 

check for vaccum leaks? then do a compression check.

 

is your CEL lit? If so, did you pull the codes? Rough idle can be so many things without you giving more information. When was the last time you had a tune-up? Spark plugs, wires, coil pack (cracks), PCV valve, fuel pump, fuel filter and so on are all possibilities.

 

What das said. If you don't have the manual buy one, its a great help. You can google to find out how to retrieve the codes and what they mean if you don't know how.
On this topic, has anybody broke a timing belt and gotten the 11 code? I was wondering if it's valid for all Neons.

 

When I idler pulley seized on me on the freeway, I got a camshaft sensor code.

 

I'm stuck at home baby sitting the son's Malamute while he's off for a weekend in the mountains I can't get to my Haynes manual. I was wondering what the sensor fault code number is.
