Wow. You joined in December '06 and this is your first post? WOW!

Please click the User CP link and complete your profile for the forum to including your vehicle and location (heavily suggested by your username, but helpful nonetheless).

Warning lights are not the only issue (aside from the point that bulbs can burn out). Get a code reader and scan for codes. Codes can store in the absence of a CEL and can point the way to the problem.

Assuming you've regularly changed your gas filter, air filter, spark plugs and other routine items this could be caused by bad connectors on the coil side of the wires, as well as one or more dirty injectors, etc.

But start with codes and go on from there.

Take care and enjoy the ride,
Greg

Vacuum hoses should be inspected any time you have unusual running issues. So sure take a look. Used carefully and with proper ventilation propane is useful for helping to locate them.

All cars marketed to the US beginning with MY 1996 comply with OBD-II standards. Any OBD-II meter will read codes, you don't need one to translate for you, just alphanumeric codes is fine. Read and erase is all you need.

You've been around a while but just started posting, may I suggest that you spend a little time reading through the titles of the DIY/Help stickies? There is a wealth of information in there, including some information about code readers and an excellent DIY for changing the fuel filter. You can indeed DIY that and autohausaz.com often has the Bosch fuel filters on sale.

Take care and enjoy the ride,
Greg
