Car hesitates!! Please help!

Sounds like you might have a fuel system issue. The Cow or the Raven would be able to help you out best, but I may be able to offer some assistance until they reply to your post.
-Check your PCV valve and make sure it's properly installed.
-Check your brake booster line and be sure it's on tight and not allowing vaccuum to escape.
-Make sure you don't have any leaks around your intake plenum or TB.
-How clean is your intake and plenum? Check inside with a flashlight for buildup. See the TB and Plenum cleaning how-to on this site. (I used three cans of bra-kleen to get my plenum clean)
-Is your air intake hose free of obstructions?
-How recently have you changed your fuel filter? It could be a small part of your problem.
-And a tune up? Dirty plugs and old wires can rob your engine of power.
-I'm not quite sure about DIS systems - I haven't had to tinker with mine yet. (I'd probably zap myself)
-Are your injectors clean and properly functioning?
-Are your injectors being fed with fuel at an even pressure?
-How clean is your oil and what viscosity do you use? Sometimes a thicker cold viscosity will provide less than optimum lower end lubrication until the oil is properly warmed. (This probably is not an issue, though I found it plays a part with my car)
-Does it burn oil? Too much oil seeping into the combustion chamber while the engine is off will cause a difficult start and rough running until the oil is burned out.
-And of course, if you have a service engine light then you should check for codes. They usually give a pretty good idea about what's wrong.
Like I said, the Cow or Raven seem to be the experts around here, so they could help you out best :wink: . Hopefully I offered some decent info that may give you some relief.

Good Luck!
