Ok. car has 103K miles. Just did waterpump and timing belt back in August. Just did spark plugs and new plug wires a couple weeks ago. Ever since then, the car has to crank over for up to 10 seconds now before starting, and it's starting really rough, either too much fuel or not enough. Smells more like too much. Also, at idle, it cuts out a bit every now and then, idling rough. Accelerates and drives totally fine, just at idle, whether in nuetral or in gear. Bad injector maybe? Malfunctioning PCM? Also, now the cruise control won't turn on....is it linked in somewhere and not turning on because of the rough idling/starting problem? can anyone help?

added *Also, the car is NOT showing check engine light and has NO codes."

I found a light at the end of a tunnel (another forum). FUEL PRESSURE REGULATOR. It's vacuum operated so when the diaphram starts leaking, it's three problems together....incorrect fuel pressure monitoring, vacuum leak, and pulling unmetered fuel directly into the intake manifold and causing the car to run rich (which would also be like the car is choking out because of too much fuel). Best part is, fuel pressure regulator is only $35 or so, found it on Amazon.com
For that price, I would say it’s worth it to change out, especially 200-2003 year Hyundais.
