I have an 04 sedona with 88,000 miles on it. Took it to the dealer to have the timing belt replaced, it was due and starting to slip. Van overheated 2 days before, dealer replaced belt, leaking radiator, head and gasket, rear aux lines and wires and plugs. Dealer mentioned funny Maf sensor readings on the sales slip, but neglected to verbally tell us. Van would hesitate upon acceleration then engine cut out while driving(accelerating) 2 days after we got it back, check engine light is ON when we got it back idling rough. Engine dies lights and accessories work still. Van won't start, after waiting 5 min. It starts then dies shortly after. Replaced maf sensor engine light went out. Drove 70 miles fine. Again check engine light comes on as van dies while driving. Towed it home and there it sits. Dealer underquoted work by $1600, blamed the new guy and gave a $1000 discount on work, called 3 hours later with ironically $1000 new work to be done. I'm not stupid, you have to make up the discount elsewhere! Totally stumped. My research shows this has happened to many other, but haven't found many answers. Supposedly engine was tuned after repair, fuel trim calibrated, but still idling rough. Maf sensor just gets plugged in when replaced, no calibration needed, Am I right? What else should I check? My thoughts are fuel system or ecm. How do I check the fuel system? Could the dealership have screwed up the fuel trim, how do I check and fix it?
