my 03 expy hesitates on acceleration and the check engine soon light begin to blink, not good with cars so just need some type of idea before going to the dealer
A coil pack may have gone bad.
If the check engine light blinks, it usually means do not drive the car!(or at least not far) I would get the code pulled at your local Autozone(they do it for free) and then report back. GL!
this is a simple repair that takes all of 15 min
that is a easy coil to replace and you might as well buy a new plug too
if i wasnt comfortable doing it myself i would just take it to your reg mechanic and see if he could do it for 25-30 bucks
If you do change plugs yourself, make sure the motor is completly cold. The threads of the plug holes are aluminum and it wouldn't take much to strip the threads. Also be careful not to overtorque the new plugs. Good luck-
