Question about 2003 Hyundai Tiburon

Code p1166 only months after New Plugs, wires, Air Filter, & OLF?

Codes p1166,uodoo,p0711,p2300(pd) I have a 2003 Hyundai Tiburon GT V6 6Spd my research reveals: Engine code P1166. Can be (Fuel pressure too high, Fuel pressure regulator Fault, or Failed injectors.) I changed the Intake Air Filter (aftermarket K&N drop in). The light went on like 2 months after I installed the New Air filter. I then had the oil changed (synthetic), new plugs top of line iridium, & new wires also high end. The mechanic did the work and said I need a PCV Valve and an air filter gasket...? Only a few extra bucks but the light was out. I did notice the performance seemed poorer (top end RPMs seemed to dip) and 2 months later the light is on and indicates O2 sensor or Fuel injectors. Any hints on what?s what?

Code U0000 The problem is with a Hyundia Sonata 2.5 L V6 P0711 the engine starts and runs for two seconds and then p2300 shuts off. The fuel pump works,...


there is no factory code uoooo, if you took it to auto zone or pep boys they used a generic scan tool, however po711 is a transmission code, sounds like a bad cranksensor, or a camsensor fault, save yourself alot of money dont throw parts at it, take it to the dealer, they know the product, and have the factory scan tool,

2003 Tiburon GT-V6, Air Bag light has come on and stays on, PLEASE tell me how to fix without going to the Dealer, Local Dealer has mixed service results


Sorry. The airbag system is propietary to Hyundai manufacturing. The Diagnostic Trouble Codes (DTC's) in the Supplememental Restraint System (SRS) are unique to Hyundai - unavoidable unless you can find a High-Scan Pro scanned to pull the code and get the wiring diagrams to solve this. Solution is the Dealer - pay the diag fee and they will give you an estimate of repairs (parts, labor, tax, time-frame, etc)... I know this isn't what you want to hear.. but it's Hyundai's system and only Hyundai has the solution.

Code p0335, and jerkinging problem with pending codes p02300 and p0711


THE INTERMITTENT SIGNAL FROM THE DEFECTIVE CRANK SENSOR IS CAUSING THE CAR TO STARVE OF SPARK AND FUEL. IF YOU REPLACE THE CRANK SENSOR, THIS WILL FIX THE JERKING PROBLEM BY HAVING A CONTINUOUS FLOW OF FUEL AND SPARK. THE TRANSMISSIONS ON THESE CARS ARE NOTORIOUS FOR SHIFTING PROBLEMS. THE TRANSMISSION MAY NEED A NEW FILTER AND FLUID. HOPE THIS HELPS. KEEP ME POSTED PLEASE. THANKS FOR AN HONEST RATING AND FOR USING FIX-YA. GOOD LUCK

2003 Tiburon GT, RPM's drop way down and idles rough at stop's?


More maintenance history needed. Oil changed regularly, timing belt replaced at 60 K miles, Engine air filter & intake air hose inspection?
Causes of the problem you describe are many. Recommend you have a technician check your throttle position sensor for any bad spots in the potentiometer... most likely cause when there is NO Check Engine light.
